MC1455P1, MC1455 Datasheet (ON Semiconductor)

MC1455P1, MC1455, Timers

MC1455, MC1455B, NCV1455B Timers The MC1455 monolithic timing circuit is a highly stable controller capable of producing accurate time delays or oscillation.

Additional terminals are provided for triggering or resetting if desired.

In the time delay mode, time is precisely controlled by one external resistor and capacitor.

For astable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor.
