CD4541 - PROGRAMMABLE TIMER CMOS IC

General 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.

Key Features

  • S.
  • 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).
