SN74ALVCH16903DLR TI Bus Switch | 56-SSOP | 3.3V, 20-Bit, 2-Port

Product Overview

The SN74ALVCH16903DLR is a 20-bit universal bus driver with 3-state outputs from Texas Instruments. It operates at a nominal 3.3V supply voltage and is designed for low-voltage, high-speed data bus applications. The device features two ports (A and B) with direction control (DIR) and output enable (OE) pins, making it ideal for bidirectional data flow in multiplexed bus systems. Packaged in a 56-pin SSOP (Shrink Small Outline Package), it offers a compact solution for space-constrained designs.
