ISL59452

Data Sheet

September 24, 2007

FN6254.0

Triple 4:1 Single Supply Video

Multiplexing Amplifier

The ISL59452 is a 4-input, single-supply, triple video

multiplexer suited for component video applications. The

device features single +5V supply operation, high bandwidth

and TTL/CMOS logic compatible gain select (AV2) of x1 or

x2. When HIZ is pulled high, the outputs are put into high-

impedance states and the video inputs are disconnected

putting the device in a low power state. This is an essential

feature for power sensitive applications. The ISL59452 also

features fast channel switching at pixel rates to allow for

video overlays.

The ISL59452 will drive 150惟 loads making it suitable for

75惟 cable driving applications. The ISL59452 is ideal for

RGB, YPbPr, as well as S-Video and composite

applications.

The ISL59452 comes in a 32 Ld QFN package and is

specified for operation over -40擄C to +85擄C temperature

range.
