U74CBTLV3251 Datasheet
  

LOW-VOLTAGE 1-OF-8 FET MULTIPLEXER/DEMULTIPLEXER

 

 

DESCRIPTION

 

The U74CBTLV3251 device is a 1-of-8 high-speed FET

multiplexer/demultiplexer. The low on-state resistance of the switch

allows connections to be made with minimal propagation delay.

The select inputs (S0, S1, S2) control the data flow. The FET

multiplexers/demultiplexers are disabled when the output-enable (OE )

input is high.

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.

To ensure the high-impedance state during power up or power

down, OE should be tied to VCC through a pull-up resistor; the

minimum value of the resistor is determined by the current-sinking

capability of the driver.

 

FEATURES

 

* 5Ω Switch Connection Between Two Ports

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

* IOFF Supports Partial-Power-Down Mode Operation
