Hi,
I have to design an EPROM programmer for 2716. But the EPROM chip requires a VPP input of 25V when being programmed and a VPP input of 5V when being read.I have to change these voltages alternately using software as I have to first check if the address is empty and then program it. I'm allowed to use any device .
plz suggest.....![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
