Supports Partial-Power-Down Mode

Operation

This single-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is

designed to track V

CCA

. V

CCA

accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track

CCB

. V

CCB

accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional

translation between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.

The SN74LVC1T45 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 I

and I

CCZ

The SN74LVC1T45 is designed so that the DIR input is powered by V

CCA

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 V

isolation feature ensures that if either V

input is at GND, then both ports are in the high-impedance

state.
