RHD 5912 Quad Comparator, Open Drain Outputs

The RHD5912 integrates four continuous comparators with open-drain outputs. The comparators accept dynamic signals at either or both inputs and provide digital indications of the comparison result. Diode protection is included at inputs and outputs, and the CMOS design tolerates momentary shorts. Internal hysteresis is present, but applications with slowly changing signals may still require external feedback to avoid noise-driven chatter. The device uses circuit and layout methods intended to mitigate ionizing-dose effects and single-event latchup. The exact ordering suffix determines the applicable screening flow and radiation assurance.
