HCPL-3700-000E

The 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
