MC14541BDTG General Description

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 V_DD 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 16-stage counter divides the oscillator frequency (f_ocs with the n^th stage frequency being f_osc/2ⁿ.
