EL4340, EL4342

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.

NOTES:

1. Add “-T13” or “-T7” suffix for tape and reel. Please refer to TB347

for details on reel specifications.

2. These Intersil Pb-free plastic packaged products employ special

Pb-free material sets, molding compounds/die attach materials,

and 100% matte tin plate plus anneal (e3 termination finish,

which is RoHS compliant and compatible with both SnPb and

Pb-free soldering operations). Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or

exceed the Pb-free requirements of IPC/JEDEC J STD-020.
