The MC14541B programmable timer includes a 16-stage binary counter, integrated oscillator for an external capacitor and two resistors, automatic power-on-reset circuitry, and output control logic. Timekeeping is initialized by power-on, at which point power-on-reset is enabled and the counter is initialized within the specified VDD range. When the power is turned on, an external reset pulse can be applied. When the initial reset command is issued, the oscillator will oscillate at a frequency determined by the external RC network. This 16-stage counter divides the oscillator frequency (focs) by the nth stage frequency equals fosc/2n.

The MC1455 monolithic timer circuit is a very stable controller capable of generating accurate time delays or oscillations. Additional terminals are available for trigger or reset if required. In time-delay mode, the timing is precisely controlled by an external resistor and capacitor. For stable operation as an oscillator, both the idle frequency and duty cycle are accurately controlled with two external resistors and a capacitor. The circuit can be toggled and reset on falling waveforms and the output structure can source/sink up to 200 mA or drive a TTL circuit.
