HCPL3700-000EThe HCPL-3700-000E is an Isolated Voltage/Current Threshold Detection Optocoupler utilize threshold sensing input buffer ICs which permit control of threshold levels over a wide range of input voltages with a single external resistor. The input buffer incorporates several features hysteresis for extra noise immunity and switching immunity, a diode bridge for easy use with ac input signals and internal clamping diodes to protect the buffer and LED from a wide range of over-voltage and over-current transients. Because threshold sensing is done prior to driving the LED, variations in optical coupling from the LED to the detector will have no effect on the threshold levels., AC or DC input, Programmable sense voltage, Hysteresis, Logic compatible output, Thresholds guaranteed over temperature, Thresholds independent of LED optical parameters
