SN74AVC20T245DGVR TI Voltage Level Translator | 56-TVSOP | 20-bit, Dual Supply

Product Overview

The SN74AVC20T245DGVR is a 20-bit (dual-supply) voltage level translator from Texas Instruments, designed for bidirectional voltage translation between different voltage nodes in mixed-voltage systems. It operates with VCCA from 1.2V to 3.6V and VCCB from 1.65V to 5.5V, making it suitable for interfacing low-voltage ASICs/FPGAs with higher-voltage peripherals. The device features 20-bit bus-hold data inputs, output enable (OE) control, and is packaged in a 56-pin TVSOP (Thin Very Small Outline Package) for space-constrained applications.
