Description

The SN74CB3T3125 is a high-speed TTL-compatible FET bus switch with low ON-stateresistance (ron), allowing for minimal propagation delay. The device fullysupports mixed-mode signal operation on all data I/O ports by providing voltage translation thattracks VCC. The SN74CB3T3125 supports systems using 5-V TTL, 3.3-V LVTTL,and 2.5-V CMOS switching standards, as well as user-defined switching levels (seeTypical DC Voltage-Translation Characteristics).

The SN74CB3T3125 is organized as four 1-bit bus switches with separate output-enable(1OE, 2OE, 3OE,4OE) inputs. It can be used as four 1-bit bus switches or as one 4-bit busswitch. When OE is low, the associated 1-bit bus switch is ON, and the Aport is connected to the B port, allowing bidirectional data flow between ports. WhenOE is high, the associated 1-bit bus switch is OFF, and the high-impedancestate exists between the A and B ports.

This device is fully specified for partial-power-down applications usingIoff. The Ioff feature ensures that damaging currentwill not backflow through the device when it is powered down. The device has isolation during poweroff.

To ensure the high-impedance state during power up or power down,OE should be tied to VCC through a pullup resistor;the minimum value of the resistor is determined by the current-sinking capability of thedriver.
