DESCRIPTION/ORDERING INFORMATION  
This 32-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 1.4 V to 3.6 V. The B port is designed to track  
VCCB. VCCB accepts any supply voltage from 1.4 V to 3.6 V. This allows for universal low-voltage bidirectional  
translation between any of the 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.  
The SN74AVCBH324245 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 is used to disable the outputs, so the buses effectively  
are isolated.  
The SN74AVCBH324245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by VCCB  
.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. Use of pullup or  
pulldown resistors with the bus-hold circuitry is not recommended.  
To ensure the high-impedance state during power up or power down, OE should be tied to VCCB through a pullup  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
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. If either VCC input is at GND,  
both ports are in the high-impedance state.
