74LVC4245AD

Octal dual supply translating transceiver; 3-state

The 74LVC4245A is an octal dual supply translating transceiver featuring 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 (OE) and a send/receive input (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedence OFF-state, effectively isolating the buses. In suspend mode, when either supply is zero, there is no current path between supplies. VCCA ≥ VCCB, except in suspend mode. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
