The EL4340 and EL4342 are fixed unity gain mux amps featuring high slew rates and excellent bandwidth for video switching. These devices feature a high impedance output state (HIZ) that enables the outputs of multiple devices to be wired together. A power-down mode (ENABLE) is included to turn off un-needed circuitry in power sensitive applications. The ENABLE pin, when pulled high, sets the EL4340 and EL4342 into standby power mode - consuming just 18mW. An added feature in the EL4340 is a latch enable function (LE) that allows independent logic control using a common logic bus.
