The HCPL3700 is an AC/DC to logic interface optocoupler designed for voltage sensing and microprocessor interfacing in industrial control applications. It features an AlGaAs LED optically coupled to a high-gain darlington output, with TTL and CMOS logic compatibility. The device is available in an 8-pin DIP package and operates over a temperature range of 0°C to 70°C with a supply voltage of 2 to 18 V. It meets UL 94 V-0 flammability rating and is UL recognized (File #E90700); the VDE variant (HCPL3700V) satisfies VDE 0884. The optocoupler provides a 2500 Vrms isolation voltage and exhibits common mode transient immunity of up to 4000 V/µs at output high level. A 0.1 µF bypass capacitor between pins 8 and 5 is required for proper operation.
