SN74AVC8T245PWR TI Voltage Level Translator | 24-TSSOP | 8-bit, 1.2-3.6V

Product Overview

The SN74AVC8T245PWR from Texas Instruments is an 8-bit dual-supply bus transceiver with configurable voltage-level translation. It operates from 1.2V to 3.6V on both VCCA and VCCB, enabling bidirectional level shifting between different voltage domains. The device is designed for asynchronous communication between two buses, with direction control via DIR and output enable via OE. Packaged in a 24-pin TSSOP, it is ideal for space-constrained applications requiring low power and high speed.
