Product Introduction
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 outputenable (\(\overline{OE}\)) input is high.
This device is fully specified for partial-power-down applications using \(I_{0H}\). 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, \(\overline{OC}\) 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.
