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.
