3 Description
The SN74CBT3251 is a 1-of-8 high-speed TTL-
compatible FET multiplexer and 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, and S0, S1, and S2 select one of the B
outputs for the A-input data.
