500MHz Triple 2:1 Gain-of-2, Multiplexing
Amplifier
The ISL59448 is a triple channel 2:1 multiplexer featuring
integrated buffers with a fixed gain of 2, high slew-rate and
excellent bandwidth for video switching. The device features
a three-state output (HIZ), which allows the outputs of
multiple devices to be tied together. A power-down mode
(ENABLE) is included to turn off un-needed circuitry in power
sensitive applications. When the ENABLE pin is pulled high,
the part enters a power-down mode and consumes just
14mW. An additional feature is a latch enable function (LE)
that allows independent logic control using a common logic
bus.

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.
