EL4340, EL4342
500MHz Triple, Multiplexing Amplifiers
The EL4340 and 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 and 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.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100% matte
tin plate termination finish, which are 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.
