Hello, We have a system that operates on 3 volts in which we are using a PIC 17C43 as the controller. We are using a PICMASTER emulator probe which must have its operating voltage in the range of 4.5 to 5.5 volts. My question is this: Does anybody know of an add on signal level translator kit for the AC175002 probe also known as PICPROBE-17A ? Granted it would only take a few 74ALVC164245 dual vcc level shifters to do the job but it still requires time to build it. regards Jerry English Harris Corp.
