LOW-VOLTAGE DUAL 1-OF-4 FET MULTIPLEXER/DEMULTIPLEXER

DESCRIPTION

The U74CBTLV3253 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 U74CBTLV3253 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.

FEATURES

* 5Ω Switch Connection Between Two Ports

* Rail-to-Rail Switching on Data I/O Ports

* IOFF Supports Partial-Power-Down Mode Operation
