The SN74CBT3257 is a 4-bit 1-of-2 high-speed TTL-compatible FET multiplexer/demultiplexer designed for efficient signal routing. It features low on-state resistance, which minimizes propagation delay, making it suitable for high-speed applications. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports input control levels compatible with TTL logic. The multiplexer/demultiplexer includes output-enable (OE) and select-control (S) inputs to facilitate the selection of the appropriate outputs for the A-input data. It is available in multiple package types, including 16-SOIC, and is rated for an operating temperature range of -40¬8C to 85¬8C. The device is compliant with halogen-free standards and has a medium popularity rating in the market. Engineers considering this component should note its suitability for applications requiring reliable signal switching with minimal delay and its compatibility with standard TTL logic levels.
