description/ordering information  
This 32-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 1.4 V to 3.6 V. The B port is designed to track  
CCA CCA  
V
. V  
accepts any supply voltage from 1.4 V to 3.6 V. This allows for universal low-voltage bidirectional  
CCB CCB  
translation between any of the 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.  
The SN74AVCB324245 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 SN74AVCB324245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by V  
.
CCB  
To ensure the high-impedance state during power up or power down, OE shall be tied to V  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
