<DIV><SPAN class=515235118-22092021>Hello SDIY Team,</SPAN></DIV>
<DIV><SPAN class=515235118-22092021></SPAN> </DIV>
<DIV><SPAN class=515235118-22092021>I know, I promised that my last posting
would be my last on this topic, but I have just one more tiny detail to share
with you.</SPAN></DIV>
<DIV><SPAN class=515235118-22092021></SPAN> </DIV>
<DIV><SPAN class=515235118-22092021>I just tested CD4024BE and CD4024BCN on the
breadboard, this time clocked by a CD40106 hex Schmitt trigger. The 40106
was powered with 15V (VDD) and 0V (VSS), and I used a 100k resistor and 100nF
cap to create a square wave oscillator with a frequency of about 120 Hz.
The output of this oscillator is a perfect pulse wave that oscillates
between 15V and 0V.</SPAN></DIV>
<DIV><SPAN class=515235118-22092021></SPAN> </DIV>
<DIV><SPAN class=515235118-22092021>Results: No change. CD4024BCN clocked
normally. CD4024BE clocked backwards.</SPAN></DIV>
<DIV><SPAN class=515235118-22092021></SPAN> </DIV>
<DIV><SPAN class=515235118-22092021>If I have time today, I'm going to swing by
Lee's Electronic Components on my way home and buy a few new CD4024BE chips to
test.</SPAN></DIV>
<DIV><SPAN class=515235118-22092021></SPAN> </DIV>
<DIV><SPAN class=515235118-22092021>If I get some new chips, and the results are
any different, I'll let y'all know. Otherwise, this is my last word on the
topic.</SPAN></DIV></BODY></HTML>
