DATASHEET EL4340, EL4342 FN7421 Rev.4.00 500MHz Triple Multiplexing Amplifiers Oct 4, 2017 The EL4340, EL4342 are fixed unity gain mux amps featuring Features high slew rates and excellent bandwidth for video switching. Triple 2:1 and 4:1 multiplexers for RGB These devices feature a high impedance output state (HIZ) that enables the outputs of multiple devices to be wired together. A Internally set gain-of-1 power-down mode (ENABLE) is included to turn off un-needed High speed three-state outputs (HIZ) circuitry in power sensitive applications. The ENABLE pin, when pulled high, sets the EL4340, EL4342 into standby power Power-down mode (ENABLE) mode - consuming just 18mW. An added feature in the EL4340 is a latch enable function (LE) that allows independent Latch enable (EL4340) logic control using a common logic bus. 5V operation 870 V/s slew rate Ordering Information 500MHz bandwidth PART NUMBER PART PACKAGE PKG.
