MC14541BDG

MC14541BDG 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 contro 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 wil oscillate with a frequency determined by the external RC network.
The 16−stage counter divides the oscillator frequency (fosc) with the nth stage frequency being fosc/2n. MC14541BDG
