description/ordering information

The SN74CBTLV16292 is a 12-bit 1-of-2

high-speed FET multiplexer/demultiplexer. The

low on-state resistance of the switch allows

connections to be made with minimal propagation

delay.

When the select (S) input is low, port A is

connected to port B1, and RINT is connected to

port B2. When S is high, port A is connected to

port B2, and RINT is connected to port B1.

This 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.
