description

The SN74CBTLV3257 is a 4-bit 1-of-2 high-speed FET multiplexer/demultiplexer. The low on-state resistance

of the switch allows connections to be made with minimal propagation delay.

The select (S) input controls the data flow. The FET multiplexers/demultiplexers are disabled when the

output-enable (OE) input is high.

To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup

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

The SN74CBTLV3257 is characterized for operation from –40°C to 85°C.
