General Description

The EL4331C is a triple, very high speed, 2:1 Multiplexing Amplifier.

It is intended primarily for component video multiplexing, and is espe-

cially suited for pixel switching. The amplifiers have their gain set to

1, internally. All three amplifiers are switched simultaneously from

their A to B inputs by the TTL/CMOS compatible, common A/B con-

trol pin.

The EL4331C has a power down mode, in which the total supply cur-

rent drops to less than 1 mA. In this mode, each output will appear as

a high impedance.

The EL4331C runs from standard ±5V supplies, and is available in the

narrow 16-pin small outline package.
