Data Sheet September 21, 2005

1GHz, 4 x 1 Multiplexing Amplifier with
Synchronous Controls

The ISL59444 is a single-output 4:1 MUX-amp. The MUX-amp
has a fixed gain of 1 and a 1GHz bandwidth. The ISL59444 is
ideal for professional video switching, HDTV, computer
display routing, and other high performance applications.

The device contains logic inputs for channel selection (S0,
S1), latch control signals (LE1

, LE2), and a three-state
output control (HIZ) for individual selection of MUX amps
that share a common video output line. All logic inputs have
pull-downs to ground and may be left floating.

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
are at the specified temperature and are pulsed tests, therefore: T
