This is a timing circuit that will turn on up to eight different zones ... The longest a zone will ever be on is 30 minutes. An LM555 timer may work but I wonder if I need 8 of them or if something ...
It is not completely clear from your description how the LM555 will be applied within the push-pull converter circuit. You mention that Vin is 24 V, and the outputs are +/-15 V. The LM555 has a ...
The circuit may be triggered and reset on falling waveforms, and he output circuit can source or sink up to 200mA or drive TTL circuits. The circuit is connected such that it will trigger itself and ...
