Datasheet

1. General description
The CBT3251 is a 1-of-8 high-speed TTL-compatible FET multiplexer/demultiplexer. The
low ON-resistance of the switch allows inputs to be connected to outputs without adding
propagation delay or generating additional ground bounce noise.
When output enable (OE
) is LOW, the CBT3251 is enabled. S0, S1 and S2 select one of
the Bn outputs for the A input data.
The CBT3251 is characterized for operation from 40 C to +85 C.
2. Features and benefits
