Hi John, Is the NEC PS2502-2 available where you are? This part is compatible to the LVT827. The critical parameter is the "Current Transfer Ratio" - this should be 100x or better. You should also have as fast Ton/Toff time as possible as well. If you have any other questions, please drop me a line directly. myke ----- Original Message ----- From: JP.BROWN To: Sent: Wednesday, September 29, 1999 5:56 AM Subject: YAP LVT827 ??? > Hi Y'all > > I am trying to build a YAP style Pic programmer but I can't find > any source or information on an LVT827 opto coupler, anyone know if this > is the same thing as a Sharp PC827 opto coupler? > > Anyone out there built a YAP programmer?, any comments?. > > Thank's for any information ---------- John > ----- John P.
