Product Overview
The SN74CBTLV3253D from Texas Instruments is a high-performance 2:1 multiplexer/demultiplexer with 4-bit bus switch functionality. It operates from a 2.3V to 3.6V supply, making it ideal for low-voltage applications. The device features low ON-state resistance (5 Ω typical) and fast switching speeds (tpd = 0.25 ns max). Packaged in a 16-pin SOIC, it supports bidirectional data flow and is designed for hot insertion.
