MC1455, MC1455B, NCV1455B Timers - ON Semiconductor
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 MARKING. external resistors and one capacitor. The circuit may be triggered and DIAGRAMS. reset on falling waveforms, and the output structure can source or sink up to 200 mA or drive TTL circuits. 8. SOIC 8 1455x Features 8 D SUFFIX ALYW.
