Programmable Timer

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

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. The
