ISL59452
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 150Ω loads making it suitable for
75Ω 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°C to +85°C temperature
range.
