SDN139

SDN139 Analog High Speed Optocoupler 100KBd, Photodiode with Darlington Output Description The SDN139 consists of a highly efficient AlGaAs Light Emitting Diode and an integrated high gain photo detector to provide extremely high current transfer ratio between input and output. Separate pins for the photodiode and output stage result in TTL compatible saturation voltage and high speed operation. Where desired the VCC and VO terminals may be tied together to achieve conventional photo Darlington operation. A base access terminal allows a gain bandwidth adjustment to be made. The SDN139 comes standard in an 8 pin DIP package.
