description

The SN74CBTL V3253 is a dual 1-of-4 high-speed FET multiplexer/demultiplexer . The low on-state resistance
of the switch allows connections to be made with minimal propagation delay.

The select (S0, S1) inputs control the data flow. The FET multiplexers/demultiplexers are disabled when the
associated output-enable (OE) input is high.

T o 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.

The SN74CBTLV3253 is characterized for operation from –40°C to 85°C.
