Are you looking for a device that can regulate the input voltage to your circuit? The TXS0108ERGYR level translator from Texas Instruments is your perfect solution. It is an eight-bit bidirectional voltage level translator with an open-drain output, making it the best choice for power management. This article will introduce its specifications, structure and working principle so that you can better apply this level translator.
A level translator is a voltage conversion device. It can provide one-way conversion and two-way conversion, as well as single-power and dual-power conversion. In the design of new generation electronic circuits, with the introduction of low-voltage logic, the problem of input or output logic incompatibility often occurs within the system, thus increasing the complexity of system design. For example, when a 1.8V digital circuit communicates with an analog circuit working at 3.3V, the problem of conversion between the two levels needs to be solved first, and a level translator is needed.
The TXSO108ERGYR represents a non-directional voltage level translator manufactured by Texas Instruments to proficiently convert logic voltage levels, catering to both open-drain and push-pull applications. Functioning as a non-inverting converter, this device leverages two independently configurable power rails, exemplifying versatility in its design. Classified under the integrated circuits category, it adopts the SMD or SMT mounting style, boasting compact dimensions with a length of 4.5 mm and a width of 3.5 mm. Operating within a broad temperature range from -40°C to 85°C, this voltage level translator exhibits resilience to diverse environmental conditions. Notably, the chip demonstrates a propagation delay time of 312 ns, coupled with a data rate of 60 Mb/s, ensuring swift and reliable signal translation for a spectrum of applications.

This converter uses two independent configurable power rails. The A port is designed to track VCCA and accept any supply voltage from 1.65 to 3.6V. VCCA must be less than or equal to VCCB. The B port is designed to track VCCB and accept any supply voltage from 1.65 to 5.5V. This allows universal low-voltage bidirectional conversion between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V voltage nodes. When the Output Enable (OE) input is low, all outputs are placed in a high-impedance state. The TXS0108ERGYR is designed so that the OE input circuit is provided by VCCA. To ensure a high-impedance state during power-up or power-down, OE should be connected to GND through a pull-down resistor.
The device uses a pass-gate architecture with edge rate accelerators to increase overall data rates. Pull-up resistors are commonly used in open-drain applications and can be easily integrated so no external resistors are required. Although the device is designed for open-drain applications, the device can also convert push-pull CMOS logic outputs. Its functional block diagram is as follows:
• TXS0108ERGYR is a bidirectional voltage level translator.
• TXS0108ERGYR is manufactured by Texas Instruments.
• It adopts SMD or SMT mounting method.
• Its data rate is 60 Mb/s.
• Its propagation delay time is 312 ns.
• Its operating temperature is -40°C to 85°C.
• Its power supply voltage is 1.2V to 5.5V.
• It has 20 pins and comes in VQFN package and Tape & Reel (TR) packaging.
This is operating free-air temperature range (unless otherwise stated).
Equipment should avoid exceeding its absolute maximum ratings as this may cause permanent damage. Additionally, these pressure ratings do not imply that the equipment will operate properly under these or other conditions beyond the recommended operating conditions, and prolonged exposure to these conditions may affect the reliability of the equipment. At the same time, adhering to the input and output current ratings may result in exceeding the input and output negative voltage ratings, so it is recommended to use the values in the operating conditions table.
The TXS0108ERGYR has the following functions:
• High-speed transmission: This level shifter supports data transmission rates of up to 100 Mbps, making it suitable for high-speed data communication needs.
• Wide supply voltage range: Wide supply voltage range: It supports a wide supply voltage range, from 1.2V to 3.6V, suitable for many different application scenarios.
• Bi-directional data transmission: It is capable of converting signals from one level domain to another, realizing bi-directional data transmission.
• Low power consumption: TXS0108ERGYR has excellent electrostatic discharge (ESD) protection, providing protection for signal lines and chips.
• Automatic Data Direction Detection: The TXS0108ERGYR is able to automatically detect the data direction and perform level shifting as needed without the need for external control lines.
TXS0108ERGYR is mainly used for data transmission between devices with different levels, such as televisions, smart phones, tablet PCs, digital cameras, etc. The product can connect devices with different levels together to realize bi-directional data transmission and improve compatibility and interoperability between devices. At the same time, due to the high-speed transmission and low-power design, it can also be applied to occasions that require high-speed data transmission and low-power consumption, such as smart wearable devices and smart homes, etc.
The TXSO108ERGYR is a device for level shifting applications to interconnect devices or systems operating at different interface voltages. The device is well suited for use in applications where open-drain drivers are connected to data I/Os, as well as applications where push-pull drivers are connected to data I/Os, but the TXBO104 device (SCES650) 4-bit bi-directional voltage level shifter may be a better choice for such push-pull applications. The device is a semi-buffered auto-direction-sensing voltage converter designed to be optimized for conversion applications (e.g., MMC card interfaces) that require the system to start up in a low-speed open-drain mode and then switch to a high-speed push-pull mode.
Frequently Asked Questions
1. Does the TXS0108ERGYR have built-in ESD protection?
Yes, the TXS0108ERGYR usually comes with built-in electrostatic discharge (ESD) protection, which helps safeguard the device against damage from static electricity during handling and operation.
2. What is the level shifter on a txs0108e?
This device is a 8-bit non-inverting level translator which uses two separate configurable power-supply rails. The A port tracks the VCCA pin supply voltage. The VCCA pin accepts any supply voltage between 1.4 V and 3.6 V. The B port tracks the VCCB pin supply voltage.
3. How do I choose a level shifter?
Some ICs operate from a single power supply while others operate from dual power supplies. Single-supply CMOS logic and L-MOS ICs provide a level-shifting function (TTL-level input, input-tolerant function, or open-drain output). To select the right IC, check the supply voltage range and the input VIH specification.
