The HCPL-3700S is a surface mount AC/DC to logic interface optocoupler featuring an AlGaAs LED optically coupled to a high-gain Darlington output, designed for voltage sensing and microprocessor interfacing in industrial control applications. It supports input threshold detection from 2 V to 18 V and provides TTL and CMOS logic compatibility. The device is packaged in a surface mount lead bend configuration with a maximum operating temperature range of 0°C to 70°C and supply voltage from 2 V to 18 V. An internal input buffer allows programmable sensing thresholds via an external resistor, and a 0.1 µF bypass capacitor is required between pins 8 and 5. The optocoupler meets UL 90700 and VDE0884 standards when ordered with the V option. Maximum input current is 50 mA, and output current is limited to 30 mA.
