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.Related Literature• AN1182, EL4340EVAL1 Evaluation Board User's Guide• AN1193, ISL59445/EL4342E1 Evaluation Board User's GuideFeatures• 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• Typical supply currents 10mA/ch (EL4340) and 15.3mA/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 equipmentOrdering InformationPART NUMBERPARTMARKINGTAPE &REELPACKAGEPKG.DWG. #EL4340IUEL4340IU-24 Ld QSOPMDP0040EL4340IU-T7EL4340IU7”24 Ld QSOPMDP0040EL4340IU-T13EL4340IU13”24 Ld QSOPMDP0040EL4340IUZ(Note)EL4340IUZ-24 Ld QSOP(Pb-free)MDP0040EL4340IUZ-T7(Note)EL4340IUZ7”24 Ld QSOP(Pb-free)MDP0040EL4340IUZ-T13(Note)EL4340IUZ13”24 Ld QSOP(Pb-free)MDP0040EL4342ILZA(Note)4342ILZ-32 Ld Exposed Pad3.6x4.6 QFN(Pb-free)MDP0046EL4342ILZA-T7(Note)4342ILZ7”32 Ld Exposed Pad3.6x4.6 QFN(Pb-free)MDP0046EL4342ILZA-T13(Note)4342ILZ13”32 Ld Exposed Pad3.6x4.6 QFN(Pb-free)MDP0046NOTE: 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.
