General Description
The EL4332C is a triple very h igh spee d 2:1 Mu ltip le xe r-Ampli fie r. It
is intended primarily for component video multiplexing and is especially suited for pixel switchin g. The amplifiers ha ve the ir gain set to 2
internally, which reduces the need for many external components. The
gain-of-2 facilitates driving back terminated cables. All three amplifiers 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 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.
