SN74CBT3244DBQR TI Bus Switch | 20-SSOP | 4-Bit, 2-Port, 5V

Product Overview

The SN74CBT3244DBQR from Texas Instruments is a high-performance 4-bit, 2-port bus switch designed for bidirectional signal routing. It features low on-state resistance (5 Ω typical) and wide voltage range (4.5V to 5.5V), making it ideal for bus isolation and multiplexing in digital systems. Housed in a compact 20-SSOP package, it supports hot insertion and offers low power consumption.
