DESCRIPTION

SA00533

The CBTS3257 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.

NOTES:

1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the

device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to

absolute-maximum-rated conditions for extended periods may affect device reliability.

2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
