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 2ⁿ frequency divider or as single transition timer
* 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
* oscillator
* Available division ratios 2⁸, 2¹⁰, 2¹³, or 2¹⁶
* High noise immunity: 0.45 V_DD (typ)
* 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
* range
