This TTL circuit uses LED indicators and must be powered by a voltage of 5 V. The capacitor determines the speed of the draw. We found it in documentation from the 90s.
This circuit is from a publication by Newton C. Braga in the United States. The transistor can be...
Based on the MC1488 or MC1489 operational amplifiers, this circuit has a 5000V isolation driving a...
This circuit was found in a Linear Technology manual from the 1990s. The component is the LTC1453...
