description/ordering information

The SN74CBTLV3251 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 ow. The FET multiplexers/demultiplexers are disabled when

the output-enable (OE) input is high.

This device is fully specied 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 pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
