General Description
The HMC194MS8 & HMC194MS8E are low-cost
SPDT switches in 8-lead MSOP packages for use in
applications which require high isolation between two
RF paths. The devices can control signals from DC to
3 GHz and have been optimized to provide extremely
high isolation with minimal insertion loss in medium
and low power applications. On chip circuitry allows
positive voltage control operation at very low DC cur-
rents with control inputs compatible with CMOS and
most TTL logic families. RF1 and RF2 are reflective
opens when “OFF”.
