HCPL-3700 A3700 AC/DC To Logic Interface Optocoupler IC DIP-8 Package

The HCPL-3700 voltage/current threshold detection optocoupler consists of an AlGaAs LED connected to a threshold sensing input buffer IC which are optically coupled to a high gain Darlington output. The input buffer chip is capable of controlling threshold levels over a wide range of input voltages with a single resistor. The output is TTL and CMOS compatible.

Applications:

1. Low voltage detection
2. 5 V to 240 V AC/DC voltage sensing
3. Relay contact monitor
4. Current sensing
5. Microprocessor Interface
6. Industrial controls

Features:

1. AC or DC input
2. Programmable sense voltage
3. Logic level compatibility
4. Threshold guaranteed over temperature (0? to 70?)
5. Optoplanar? construction for high common-mode immunity
6. UL recognized (file # E90700)
7. VDE certified ? ordering option ?V?, e.g., HCPL3700V
