8.1 Overview

The SN74LVC8T245 is an eight bit non-inverting bus transceiver with configurable dual power supply rails that enables bidirectional voltage level translation. Pin Ax and direction control pin are support by VCCA and pin Bx is support by VCCB. The A port is able to accept I/O voltages ranging from 1.65 V to 5.5 V, while the B port can accept I/O voltages from 1.65 V to 5.5 V. The high on DIR allows data transmission from A to B and a low on DIR allows data transmission from B to A. For voltage level translation below 1.65 V, see TI AXC products.
