SN74AVCH4T245D TI Voltage Level Translator | 16-SOIC | 4-Bit, Dual-Supply, Auto Direction

Product Overview

The SN74AVCH4T245D is a 4-bit non-inverting bus transceiver from Texas Instruments, designed for asynchronous communication between two data buses. It operates with dual supply voltages (VCCA and VCCB) ranging from 1.2V to 3.6V, making it ideal for voltage level translation in mixed-voltage systems. The device features automatic direction sensing, eliminating the need for a direction control pin. Housed in a 16-pin SOIC package, it supports partial-power-down mode and is fully specified for partial-power-down applications using Ioff. The SN74AVCH4T245D is part of TI's AVC family, offering high-speed operation with low power consumption.
