description /ordering information The SN74CBT3257 is a 4-bit 1-of-2 high-speed TTL-patible FET multiplexer/demultiplexer. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. Output-enable (OE) and select-control (S) inputs select the appropriate B1 and B2 outputs for the A-input data.
