Re: gated comparator stuck

2004-03-06 by peng3002

Spoke too soon. Output 5 still stuck on and it outputs 15V ( the
other outs put out around 11V.

note: worked perfectly when I originally finished the module. The
problem didn't arise until I switched all the 2.2K resistors to 15K
(to make the LEDs dimmer). Do you think it's a bad component
somewhere or are the new resistor values *!@#*!ing it up?

Thanks again,
Peng
