HCPL-3700 [Avago]

The HCPL-0370/3700 and HCPL-3760 are isolated voltage/current threshold detection optocouplers. The HCPL-3760 is a low-current version using a high-efficiency AlGaAs LED. They feature programmable sense voltage, hysteresis for noise immunity, logic compatible output, and thresholds guaranteed over temperature and independent of LED optical parameters. The input buffer includes hysteresis, a diode bridge for AC input, and internal clamping diodes for over-voltage and over-current protection. Recognized under UL 1577 and CSA approved for dielectric withstand proof test voltage of 3750 Vac.
