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.
