500MHz Triple, Multiplexing Amplifiers

The EL4340, 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, 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.
