can somebody help me with the equivalent of DS275 Ic.
schematic , pin diagram attached
im planning to build a programmer for 89c51/52
**broken link removed**
DS275 is not available and im running short of time as my last date for submission of project is too near. help would be greatly appreciated
A pin compatible part probably isn't available - Dallas semi got acquired by www.maxim-ic.com, and unless you want to try getting a sample directly from them, it's probably easier to work around it.
Use a more standard MAX232 chip (google and you'll find a lot of schematics)
I'm looking for a complete on line IC cross ref equivalents list.
For instance - to find an equiv for an MLM324 quad opamp -
Sounds simple enough doesn't it.
