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.
