74LVC4245ABQ-Q100

Octal dual supply translating transceiver; 3-state

The 74LVC4245A-Q100 is an octal dual supply translating transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. It is designed to interface between a 3 V and 5 V bus in a mixed 3 V and 5 V supply environment.

The device features an output enable input (pin OE) for easy cascading and a send/receive input (pin DIR) for direction control. Pin OE controls the outputs so that the buses are effectively isolated.

In suspend mode, when VCC(A) is zero, there is no current flow from one supply to the other supply. The A-outputs must be set 3-state and the voltage on the A-bus must be smaller than Vdiode (typical 0.7 V).

VCC(A) ≥ VCC(B), except in suspend mode.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
