Overview
The HMC550AE is a low-cost Single-Pole Single-Throw (SPST) Failsafe switch produced by Analog Devices Inc. This device is housed in a 6-lead SOT26 plastic package and is designed for switching applications that require low insertion loss and very low current consumption. The HMC550AE is particularly suited for IF and RF applications, including RFID, ISM, automotive, and battery-powered tags and portables.
