SN74CBT6845CDW TI Bus Switch | 20-SOIC | 5V, 8-Bit, 2-Port

Product Overview

The SN74CBT6845CDW is a high-performance 8-bit bus switch from Texas Instruments, designed for bidirectional voltage translation and signal isolation. It features two ports (A and B) with a common output enable (OE) control, allowing seamless connection or disconnection of data buses. Operating from a single 5V supply, this device provides low on-state resistance (5 Ω typical) and minimal propagation delay, making it ideal for hot-swap, bus isolation, and voltage level translation applications. The 20-SOIC package ensures compact footprint for space-constrained designs.
