7.1 Overview

The SN74AVCH8T245 is an 8-bit, dual supply noninverting bidirectional voltage level translator. Pins A1 through A4, and the control pins (DIR and OE) are referenced to VCCA, while pins B1 through B4 are referenced to VCCB. Both the A port and B port can accept I/O voltages ranging from 1.2V to 3.6V. With OE set to low, a high on DIR allows data transmission from Port A to Port B, and a low on DIR allows data transmission from Port B to Port A. When OE is set to high, both Port A and Port B outputs are in the high-impedance state. For more information, see AVC Logic Family Technology and Application.
