3 Description
The SN74CBTLV3253 device is a dual 1-of-4 high-
speed FET multiplexer and demultiplexer. The low
ON-state resistance of the switch allows connections
to be made with minimal propagation delay.
The select (S0, S1) inputs control the data flow. The
FET multiplexers/demultiplexers are disabled when
the associated output-enable (OE) input is high.
The SN74CBTLV3253 device is fully specified for
partial-power-down applications using Ioff. The Ioff
feature ensures that damaging current will not
backflow through the device when it is powered
down. The device has isolation during power off.
