Product data sheet
1. General description
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 (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 V_CCA is 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 V_diode (typical 0.7 V).
V_CCA ≥ V_CCB, except in suspend mode.
