ON Semiconductor MC1455/MC1455B/NCV1455B Timers Datasheet
The document describes the MC1455, MC1455B, and NCV1455B monolithic timing circuits. These devices are capable of producing accurate time delays or oscillation in both monostable (one-shot) and astable modes. The circuit includes two comparators, a flip-flop, and a digital output, allowing it to be triggered and reset on falling waveforms.
