ISL59440
400MHz Multiplexing Amplifier
The ISL59440 is a 400MHz bandwidth 4:1 multiplexing
amplifier designed primarily for video switching. This Mux-
amp has user-settable gain and also features a high speed
three-state function 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 ENABLE pin, when pulled high,
sets the ISL59440 to the low current power-down mode for
power sensitive applications - consuming just 5mW.

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
