DESCRIPTION

The CBT3257 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 B1 and B2 outputs for the A-input data.

The CBT3257 is characterized for operation from -40 to +85

°C.
