Multiplexed-Input Video Amplifiers
The EL44XX family of video multiplexed-amplifiers offers a very quick 8ns switching time and low glitch along with very low video distortion. The amplifiers have good gain accuracy even when driving low-impedance loads. To save power, the amplifiers do not require heavy loading to remain stable. The EL4421 and EL4422 are two-input multiplexed amplifiers. The -inputs of the input stages are wired together and the device can be used as a pin-compatible upgrade from the MAX453. The EL4441 and EL4442 have four inputs, also with common feedback. These may be used as upgrades of the MAX454. The EL4443 and EL4444 are also 4-input multiplexed amplifiers, but both positive and negative inputs are wired separately. A wide variety of gain- and phase-switching circuits can be built using independent feedback paths for each channel. The EL4421, EL4441, and EL4443 are internally compensated for unity-gain operation. The EL4422, EL4442, and EL4444 are compensated for gains of +2 or more, especially useful for driving back-matched cables. The amplifiers have an operational temperature of -40°C to +85°C and are packaged in plastic 8- and 14-pin DIP and 8and 14-pin SO. The EL44XX multiplexed-amplifier family is fabricated with Elantec's proprietary complementary bipolar process which gives excellent signal symmetry and is very rugged.

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
