This switch offers high isolation, low insertion loss, and on-chip termination of the isolated ports. The switch operates with a negative supply voltage range of −5 V to −3 V and requires two negative logic control voltages. The HMC641ALP4E includes an on-chip, binary 2 to 4 line decoder that provides logic control from two logic input lines. The HMC641ALP4E comes in ...
