Optocoupler/LED/nixie tube/photoelectric device

The FOD819 includes a gallium arsenide (GaAs) infrared emitting diode within a 4-pin dual inline plug-inencapsulation driving a silicon photo-darlington output with an integrated base emitter resistor RBE. It is suitable as a higher performance replacement for the popular FOD817 series when higher speed performance is required in isolated data signal transmission.

The HCPL3700M Voltage/Current Threshold Sensing Optocoupler consists of an AlGaAs LED connected to a threshold sensing input buffer IC that is optically coupled to a high gain Darlington output. The input buffer chip is capable of controlling the threshold level over a wide input voltage range using a single resistor. The output is TTL and CMOS compatible.
