CD4541BM
Description The CD4541B Programmable Timer is designed with a 16-stage binary counter an integrated oscillator for use with an external capacitor and two resistors output control logic and a special power-on reset circuit The special features of the power-on reset circuit are first no additional static power consumption and second the part functions across the full voltage range (3V- 15V) whether power-on reset is enabled or disabled Timing and the counter are initialized by turning on power if the power-on reset is enabled When the power is already on an external reset pulse will also initialize the timing and counter After either reset is acplished the oscillator frequency is determined by the external RC network The 16-stage counter divides the oscillator frequency by any of 4 digitally controlled division ratios Features Available division ratios 28 210 213 or 216 Increments on positive edge clock transitions Built-in low power RC oscillator...
