General Description

The HMC284AMS8G & HMC284AMS8GE are lowcost  SPDT switches in 8-lead grounded base MSOP  packages. The design has been optimized to provide  high isolation with minimal insertion loss for medium  and low power applications. On-chip circuitry allows  positive 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.
