MC14541 Programmable Timer (SOIC14) IC

MC14541 Programmable Timer (SOIC14) IC

The MC14541B programmable timer consists of a 16−stage binary counter, an integrated oscillator for use with an external capacitor and two resistors, an automatic power−on reset circuit, and output control logic. Timing is initialized by turning on power, whereupon the power−on reset is enabled and initializes the counter, within the specified VDD range. With the power already on, an external reset pulse can be applied. Upon release of the initial reset command, the oscillator will oscillate with a frequency determined by the external RC network.
