Does anyone have experience with the zsct1555 timer chip made by Zetex? I can't seem to get it to oscillate properly. My values for vcc and components are as follows:
Vcc=1.5v Ra=220 ohm Rb=3200 ohm Ct=100uf
If you know of any other chips currently in production that will produce a square-wave(does not need to be clean) output at 1hz using only a 1.5 volt battery(.9-1.5v) and a few components, I would be interrested in hearing from you. thanks!
