PROGRAMMABLE TIMER



DESCRIPTION

The CD4541 programmable timer comprise 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 counter divides the oscillator

frequency by any of 4 digitally controlled division ratios.



FEATURES

* Operates at 2

* Increments on positive edge clock transitions

* Wide supply voltage range: 3.0V ~ 15V

* Built-in low power RC oscillator

* Oscillator frequency range ~ DC to 100 kHz

* External clock applied to Pin 3 can be used instead of

* Available division ratios 2

* Master reset totally independent of automatic reset operation

* Automatic reset initializes all counters when power turns on

* Q/Q select provides output logic level flexibility

* High output drive min. one TTL load

* Maximum input leakage 1μA at 15V over full temperature
