500MHz Triple 4:1 Gain-of-2, Multiplexing
Amplifier

The ISL59446 is a triple channel 4:1 multiplexer featuring
integrated amplifiers 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
(EN

ABLE) is included to turn off un-needed circuitry in power

sensitive applications. When the EN

ABLE pin is pulled high,
the part enters a power-down mode and consumes just
14mW.

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.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTE:

1. If an input signal is applied before the supplies are powered up, the input current must be limited to these maximum values.

IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests
