ISL59424, ISL59445
1GHz Triple Multiplexing Amplifiers
The ISL59424, ISL59445 are 1GHz bandwidth multiplexing
amplifiers designed primarily for video input switching.
These MUX-amps exhibit a fixed gain of 1 and also feature a
high speed three-state to enable the output of multiple
devices to be wired together. All logic inputs have pull-downs
to ground and may be left floating. The EN pin, when pulled
high, sets the ISL59424, ISL59445 in to low current
mode-consuming just 15mW. An added feature in the
ISL59424 is a latch enable function (LE) that allows
independent logic control using a common logic bus. When
LE is high the last logic state is preserved.

NOTES:
1. Please 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), please see device
information page for ISL59424 and ISL59445. For more
information on MSL please see techbrief TB363.
