The HMXCMP01 from Honeywell is a Space-Qualified Comparator that is fabricated on radiation-hardened SOI-IV Silicon-On-Insulator (SOI) CMOS process. It requires an analog supply of 4.75-5.25 V and a digital supply of 5.0 V or 3.3 V IO voltage. This comparator has a common voltage range of 0-5 V and an input offset voltage of +/- 24 mV. It has a propagation delay of less than 125 ns and output rise/fall times of 30 ns. The comparator has a low power dissipation of 200 mW and an input capacitance of less than 10 pF. It is radiation hardened up to 3x10^5 rad (Si) and qualified by 60Co testing per MIL-STD-883 Method 1019. It is designed for low input current, low offset voltage, and fast response time while operating over the full military temperature range.
