Information

The MC14541B programmable timer cosists of a 16-stage biary couter, a itegrated illator for use wi a exteral capacitor ad two resistors, a automatic power-o reset circuit, ad output cotrol logic. Timing is iitialized by turig o power, whereupo e power-o reset is eabled ad iitializes e couter, wii e specified V rage. Wi e power already o, a exteral reset pulse ca be applied. Upo release of e iitial reset commad, e illator will illate wi a frequecy determied by e exteral RC etwork. The 16-stage couter divides e illator frequecy (f wi estage frequecy beig f/2.

Key Features

  • Available Outputs 28, 210, 213 or 216
  • Increments on Positive Edge Clock Transitions
  • Built-in Low Power RC Oscillator (+/- 2% accuracy over temperature range and +/- 20% supply and +/- 3% over processing at < 10 kHz)
  • Oscillator May Be Bypassed if External Clock Is Available (Apply external clock to Pin 3)
  • External Master Reset Totally Independent of Automatic Reset Operation
  • Operates as 2n Frequency Divider or Single Transition Timer
  • Q/Qbar Select Provides Output Logic Level Flexibility
  • Reset (auto or master) Disables Oscillator During Resetting to Provide No Active Power Dissapation
  • Clock Conditioning Circuit Permits Operation with Very Slow Clock Rise and Fall Times
  • Automatic Reset Initializes All Counters On Power Up
  • Supply Voltage Range = 3.0 Vdc to 18 Vdc with Auto Reset Disabled (Pin 5 = VDD)
    8.5 Vdc to 18 Vdc with Auto Reset Enabled (Pin 5 = VSS)
  • These Devices are Pb−Free and are RoHS Compliant
