description/ordering information  
This 4-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is  
designed to track V . V accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track  
CCA CCA  
V
. V  
/V  
accepts any supply voltage from 1.2 V to 3.6 V. The SN74AVC4T245 is optimized to operate with  
CCB CCB  
V
set at 1.4 V to 3.6 V. It is operational with V  
low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.  
/V  
as low as 1.2 V. This allows for universal

CCA CCB  
The SN74AVC4T245 is designed for asynchronous communication between data buses. The device transmits  
data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the  
direction-control (DIR) input. The output-enable (OE) input can be used to disable the outputs so the buses are  
effectively isolated.  
The SN74AVC4T245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by V  
.

This device is fully specified for partial-power-down applications using I . The I circuitry disables the outputs,

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

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
