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-k 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-k resistors. If VCCA = 0 V, the A-port and B-port I/Os are disabled (Hi-Z).
