1. General description

The 74AVC2T245-Q100 is a 2-bit, dual supply transceiver that enables bidirectional level

translation. The device can be used as two 1-bit transceivers or as a 2-bit transceiver. It features

two 2-bit input-output ports (An and Bn) and direction control inputs (DIRn), an output enable input

(OE) and dual supply pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(B) can be supplied at any

voltage between 0.8 V and 3.6 V making the device suitable for translating between any of the low

voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). Pins An, OE and DIRn are referenced

to VCC(A) and pins Bn are referenced to VCC(B). A HIGH on DIRn allows transmission from An to Bn

and a LOW on DIRn allows transmission from Bn to An. The output enable input (OE) can be used

to disable the outputs so the buses are effectively isolated.

The device is fully specified for partial power-down applications using IOFF. The IOFF circuitry

disables the output, preventing any damaging backflow current through the device when it is

powered down. In suspend mode when either VCC(A) or VCC(B) are at GND level, both An and Bn

are in the high-impedance OFF-state.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
