1. General description

The 74LVC245A-Q100; 74LVCH245A-Q100 is an 8-bit transceiver with 3-state outputs. The device

features an output enable (OE) and send/receive (DIR) for direction control. A HIGH on OE causes

the outputs to assume a high-impedance OFF-state. Inputs can be driven from either 3.3 V or

5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V

environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

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

disables the output, preventing the potentially damaging backflow current through the device when

it is powered down.

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

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