DESCRIPTION/ORDERING INFORMATION  
This 4-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 1.2 V to 3.6 V. The B port is designed to track  
VCCB. VCCB accepts any supply voltage from 1.2 V to 3.6 V. The SN74AVCH4T245 is optimized to operate with  
VCCA/VCCB set at 1.4 V to 3.6 V. It is operational with VCCA/VCCB as low as 1.2 V. This allows for universal  
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.  
The SN74AVCH4T245 is designed for asynchronous communication between two data buses. The logic levels  
of the direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the  
A-port outputs or place both output ports into the high-impedance mode. 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 is always active and must have a logic HIGH or  
LOW level applied to prevent excess ICC and ICCZ  
.
The SN74AVCH4T245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied 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. The bus-hold circuitry on the powered-up side always stays active.

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