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.
3. For Moisture Sensitivity Level (MSL), please see device
information page for EL4340, EL4342. For more information on
MSL please see techbrief TB363.
