EL4421CS Multiplexed Input Video Amplifiers
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 amplifiers do not require heavy loading to remain stable.

Unity or a 2-gain bandwidth of 80 MHz

Directly drives high-impedance or 75X loads

70 dB off-channel isolation at 4 MHz
