Description

   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 flow of the SN74CBTLV3251. The FET multiplexers/demultiplexers are disabled when the output-enable (OE ) input is high.

   This SN74CBTLV3251 is fully specified for partial-power-down applications using I_off. The I_off 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 V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
