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” suffix for 2.5k unit or “-T7” suffix for 1k unit tape and reel
options. 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), see product information page
for EL4340, EL4342. For more information on MSL, refer to TB363.
