7.1 Overview

The SN74AVC1T45 is a single-bit, dual-supply, noninverting voltage level translation device. VCCA supports pin A and the direction control pin, and VCCB supports pin B. 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. The high on DIR allows data transmission from A to B and a low on DIR allows data transmission from B to A.
