Texas Instruments LM339D

LM339D Overview
Texas Instruments is a well-known brand in the electronics industry, known for its high-quality and reliable products. One of their popular offerings is the Linear - Comparators chip, which falls under the Linear - Comparators category. This chip is designed to provide precise comparisons between two input voltages, making it ideal for use in a variety of applications such as voltage monitoring, level shifting, and signal conditioning. The package or case for this chip is 14-SOIC (0.154, 3.90mm Width), which refers to the type of packaging used to house the chip. This package is surface mount compatible, meaning it can be directly mounted onto a circuit board without the need for additional components. This saves space and simplifies the manufacturing process, making it a popular choice for many electronic devices. When it comes to operating temperature, this chip has a range of 0°C~70°C, which indicates the temperature range in which it can function properly. This makes it suitable for use in a variety of environments, from room temperature to slightly warmer conditions. The JESD-609 Code for this chip is e4, which indicates its compliance with industry standards for handling and storage. Furthermore, this chip is also environmentally friendly, as it is Pb-free, meaning it does not contain any harmful lead components. This is denoted by the "yes" in the Pbfree Code parameter. However, it is worth noting that this chip is now obsolete, as indicated by its Part Status. This means that it is no longer being manufactured by Texas Instruments, and may be difficult to find in the market. Another important parameter to consider is the Moisture Sensitivity Level (MSL), which for this chip is 1 (Unlimited). This indicates the level of moisture exposure the chip can withstand during shipping and storage without being damaged. A level of 1 means that the chip has no moisture sensitivity, making it suitable for use in various environments. The number of terminations for this chip is 14, which refers to the number of external connections or pins on the chip. This is an important consideration when designing a circuit, as it determines the number of connections needed to integrate the chip into the system. Lastly, the Voltage - Input Offset (Max) and Current - Input Bias (Max) parameters indicate the maximum amount of voltage and current that the chip can handle without affecting its performance. In this case, the chip can handle up to 5mV of input offset voltage at 30V, and a maximum input bias current of 0.25μA at 5V. In conclusion, the Texas Instruments Linear - Comparators chip is a high-quality and versatile product that offers precise voltage comparisons in a compact and environmentally friendly package. With its wide operating temperature range, surface mount compatibility, and low input offset and bias, it is a popular choice for many electronic applications. However, its obsolescence may make it challenging to find in the market.
