description/ordering information
The SN74CBT3251 is a 1-of-8 high-speed TTL-compatible FET multiplexer/demultiplexer. The low on-state
resistance of the switch allows connections to be made with minimal propagation delay.
When output enable (OE) is low, the SN74CBT3251 is enabled. S0, S1, and S2 select one of the B outputs for
the A-input data.
