SDN135

SDN135 Analog High Speed Optocoupler 1MBd, Photodiode with Transistor Output Description The SDN135 is a high speed optocoupler consisting of an infrared GaAs LED optically coupled through a high isolation barrier to an integrated high speed transistor and photodiode. Separate access to the photodiode and transistor allow users to reduce base-collector capacitance, enabling much higher switching speeds. Signals with frequencies of up to 2.0MHz can be switched, giving the SDN135 a much broader application range than traditional optocouplers. The SDN135 comes standard in an 8 pin DIP package.
