DESCRIPTION/ORDERING INFORMATION  
The SN74AVC2T872 is a 2-bit voltage level translator optimized for use in interchip USB (IC-USB) applications.  
VCCA and VCCB can each operate over the full range of 1.1 V to 3.6 V. The device has been designed to maintain  
crossover skew to be less than 1 ns. Each B-port has an integrated 120-kΩ pulldown resistor that can be  
enabled and disabled using the PD_EN control signal. If VCCB = 0 V, the A-port I/Os are disabled (Hi-Z) and the  
B-port I/Os are held to GND through the 120-kΩ resistors. If VCCA = 0 V, the A-port and B-port I/Os are disabled  
(Hi-Z).
