产品信息

The SN74AVC1T45 is designed for asynchronous communICation between two data buses. The logic levels of

the direction-control (DIR) input activate either the B-port outputs or the A-port outputs. The device transmits data

from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the

A-port outputs are activated. The input circuitry on both A and B ports always is active and must have a logic

HIGH or LOW level applied to prevent excess ICC and ICCZ.

The SN74AVC1T45 is designed so that the DIR input is powered by VCCA.

This device is fully specified for partial-power-down applications using I

off. The I

off circuitry disables the outputs,

preventing damaging current backflow through the device when it is powered down.

The VCC isolation feature ensures that if either VCC input is at GND, then both ports are in the high-impedance

state.
