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 HEF4047B is an integrated circuit containing a gatable astable multivibrator that is incorporated with logic techniques to allow positive or negative edge-triggered monostable multivibrator action ...

In the days of large split supplies, it was relatively easy to make a good monostable multivibrator. Even 5-V single supplies posed only a moderate challenge. Making a good one-shot to run on 3.3 V is ...
