description/ordering information
The SN74CBT3253 is a dual 1-of-4 high-speed TTL-compatible FET multiplexer/demultiplexer. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. 1OE, 2OE, S0, and S1 select the appropriate B output for the A-input data.
