The 74LVC4245A 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 (pinOE) for easy cascading and a send/receive input (pin DIR) for direction control. PinOE controls the outputs so that the buses are effectively isolated.
In suspend mode, when VCCAis zero, there will be 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). VCCA≥VCCB, except in suspend mode.
Features
5 V tolerant inputs/outputs, for interfacing with 5 V logic
