SN74AVCH4T245DGVR TI Voltage Level Translator | 16-TVSOP | 4-Bit, Dual-Supply

Product Overview

The SN74AVCH4T245DGVR is a 4-bit non-inverting bus transceiver from Texas Instruments, designed for asynchronous communication between two voltage nodes. It operates with dual supply voltages from 1.2V to 3.6V on the A port and 1.65V to 3.6V on the B port, making it ideal for level translation in mixed-voltage systems. The device features direction control (DIR) and output enable (OE) pins, and supports partial power-down mode (Ioff) to prevent backflow current when powered off. Packaged in a 16-pin TVSOP, it is suitable for space-constrained applications.
