General Description
The HMC284MS8G & HMC284MS8GE are low-cost
SPDT switches in 8-lead grounded base MSOP pack-
ages. The design has been optimized to provide high
isolation with minimal insertion loss for medium and
low power applications. On-chip circuitry allows posi-
tive voltage control operation at very low DC currents
with control inputs compatible with CMOS and most
TTL logic families. In the “OFF” state, RF1 and RF2
are non-reflective. See reflective high isolation SPDT
version, HMC194MS8.
