1. General description

The CBT3257A-Q100 is a quad 1-of-2 high-speed TTL-compatible 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.

Output enable (OE) and select-control (S) inputs select the appropriate nB1 and nB2 outputs for

the nA input data.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
