DESCRIPTION/ORDERING INFORMATION  
This 16-bit (dual-octal) noninverting bus transceiver contains two separate supply rails. B port has VCCB, which is  
set to operate at 3.3 V and 5 V. A port has VCCA, which is set to operate at 2.5 V and 3.3 V. This allows for  
translation from a 2.5-V to a 3.3-V environment, and vice versa, or from a 3.3-V to a 5-V environment, and vice  
versa.  
The SN74ALVC164245 is designed for asynchronous communication between data buses. The control circuitry  
(1DIR, 2DIR, 1OE, and 2OE) is powered by VCCA  
.
To ensure the high-impedance state during power up or power down, the output-enable (OE) input should be tied  
to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability  
of the driver.
