AC/DC to Logic Interface Optocouplers Technical Data HCPL-0370 HCPL-3700 HCPL-3760 Features - Standard (HCPL-0370/3700) and Low Input Current (HCPL-3760) Versions - AC or DC Input - Programmable Sense Voltage - Hysteresis - Logic patible Output - Thresholds Guaranteed over Temperature - Thresholds Independent of LED Optical Parameters - Recognized under UL 1577 and CSA Approved for Dielectric Withstand Proof Test Voltage of 3750 Vac, 1 Minute Description The HCPL-0370/3700 and HCPL-3760 are voltage/current threshold detection optocouplers. The HCPL-3760 is a low-current version of the HCPL-0370/3700. To obtain lower current operation, the HCPL-3760 uses a high-efficiency Al Ga As LED which provides higher light output at lower drive currents. The devices utilize threshold sensing input buffer ICs which permit control of threshold levels over a wide range of input voltages with a single external resistor. HCPL-0370/3700/3760 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 Functional Diagram Applications - Limit Switch Sensing - Low Voltage Detector - 5 V-240 V AC/DC Voltage Sensing - Relay Contact Monitor - Relay Coil Voltage Monitor - Current Sensing - Microprocessor Interfacing AC 1 8 VCC DC+ 2 DC- 3 AC 4 TRUTH TABLE (POSITIVE LOGIC) INPUT OUTPUT L H H L CAUTION: It is advised that normal static precautions be taken in handling and assembly of this ponent to prevent damage and/or degradation which may be induced by...
