The EL4340 and EL4342 are fixed unity gain mux ampsfeaturing high slew rates and excellent bandwidth for videoswitching. These devices feature a high impedance outputstate (HIZ) that enables the outputs of multiple devices to bewired together. A power-down mode (ENABLE) is includedto turn off un-needed circuitry in power sensitiveapplications. The ENABLE pin, when pulled high, sets theEL4340 and EL4342 into standby power mode - consumingjust 18mW. An added feature in the EL4340 is a latch enablefunction (LE) that allows independent logic control using acommon logic bus.
