FN7421.1
500MHz Triple, Multiplexing Amplifiers
Features
• Triple 2:1 and 4:1 multiplexers for RGB
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
• Internally set gain-of-1
• High speed three-state outputs (HIZ)
• Power-down mode (ENABLE)
• Latch enable (EL4340)
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.
• ±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)

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.
