CD4541 Datasheet


The UTC 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.

*Operates at 2 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
*Maximum input leakage 1μA at 15V over full temperature range
