General Description
The EL4331C is a trip le , ve ry hi gh sp eed , 2 :1 Mu ltip le x ing Am pl ifie r.
It is intended primarily for component vid eo multiple xing, and is es pecially 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 control pin.
The EL4331C has a power down mode, in which the total supply current drops to less than 1 mA. In this mode, each output will appear as
a high impedance.
The EL4331C runs fro m st an dard ±5V s uppl ie s, an d is a vai lable 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
Series system. Unless otherwise noted, all tests are pulsed tests, therefor T
= TC = TA.
