NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.


Description

The CBTLV3251 is a 1-of-8 high-speed multiplexer/demultiplexer. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.

The select input (S0, S1, S2) controls the data flow. The multiplexer/demultiplexer switches IDT74CBTLV3251 are disabled when the output-enable (OE ) input is high.

To ensure that the device is in high-impedance state during power up or power down, OE IDT74CBTLV3251 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.
