DESCRIPTION
SA00570
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.
PIN DESCRIPTION
PIN NUMBER

When output enable (OE) is low, the CBT3251 is enabled. S0, S1,
and S2 select one of the B outputs for the A-input data.

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.
