4332C
General Description
The EL4332C is a triple very high speed 2:1 Multiplexer-Amplifier. It
is intended primarily for component video multiplexing and is espe-
cially suited for pixel switching. The amplifiers have their gain set to 2
internally, which reduces the need for many external components. The
gain-of-2 facilitates driving back terminated cables. All three amplifi-
ers are switched simultaneously from their A to B inputs by the
TTL/CMOS compatible, common A/B control pin.
A -3 dB bandwidth of 300 MHz together with 3 ns multiplexing time
enable the full performance of the fastest component video systems to
be realized.
The EL4332C runs from standard 5V supplies, and is available in the
narrow 16-pin small outline package.

Important Note:
All parameters having Min/Max specifications are guaranteed. The Test Level column indicates the specific device testing actually performed during
production and Quality inspection. Elantec performs most electrical tests using modern high-speed automatic test equipment, specifically the LTX77
