7.1 Overview

The SN74AVCH4T245-Q1 is a 4-bit, dual-supply noninverting bidirectional voltage level translation device. Ax pins and control pins (1DIR, 2DIR,1 OE, and 2 OE) are supported by VCCA, and Bx pins are supported by VCCB. The A port can accept I/O voltages ranging from 1.08V to 3.6V, while the B port can accept I/O voltages from 1.08V to 3.6V. A high on DIR allows data transmission from Ax to Bx and a low on DIR allows data transmission from Bx to Ax when OE is set to low. When OE is set to high, both Ax and Bx pins are in the high-impedance state. For more information, refer to the AVC Logic Family Technology and Applications application report.
