The EL44XX family of video multiplexed-amplifiers offers a very quick 8 ns 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 am- plifiers 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 de- vice 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 amplifi-ers 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 driv- ing back-matched cables

The amplifiers have an operational temperature of- 40Cto +85C and are packaged in plastic 8- and 14-pin DIP and 8- and 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
