DESCRIPTION/ORDERING INFORMATION  
This single-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is  
designed to track VCCA. VCCA accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track  
VCCB. VCCB 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 ICC and ICCZ  
.
The SN74LVC1T45 is designed so that the DIR input is powered by VCCA  
.
This device is fully specified for partial-power-down applications using Ioff. The Ioff 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.
