SDN138
Analog High Speed Optocoupler
100KBd, Photodiode with Darlington Output
Description
The SDN138 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 V_CC and V_O terminals
may be tied together to achieve conventional photo
Darlington operation. A base access terminal allows
a gain bandwidth adjustment to be made.
The SDN138 comes standard in an 8 pin DIP package.
Applications
 Digital Logic Ground Isolation
 Replace Slower Speed Optocouplers
 Low Input Current Line Receivers
 Ring Detector Circuitry
 Loop Current Receiver
 High Common Mode Noise Line Receiver
