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.
