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 VDD (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 * Maximu.
