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.

Features

• Triple 2:1 and 4:1 multiplexers for RGB

• Internally set gain-of-1

• High speed three-state outputs (HIZ)

• Power-down mode (ENABLE)

• Latch enable (EL4340)

• ±5V operation

• ±870 V/µs slew rate

• 500MHz bandwidth

• Supply current 11mA/ch (EL4340) and 16mA/ch (EL4342)

• Pb-free plus anneal available (RoHS compliant)

Applications

• HDTV/DTV analog inputs

• Video projectors

• Computer monitors

• Set-top boxes

• Security video

• Broadcast video equipment

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.
