While choosing an op-amp buffer, some sources of negative supply were considered, because the buffer op-amp had to provide true zero voltage on its output. In reality, a typical rail-to-rail output op ...

The MM54C221/MM74C221 is a dual CMOS monostable multivibrator. Each one-shot has three inputs (A, B and CLR) and two outputs (Q and Q ). The output pulse width is set by an external RC network. The A ...
