    產(chǎn)品信息

    The MC14541B programmable timer consists of a 16-stage binary counter, an integrated oscillator for use with an external capacitor and two resistors, an automatic power-on reset circuit, and output control logic.
    Timing is initialized by turning on power, whereupon the power-on reset is enabled and initializes the counter, within the specified V
    range. With the power already on, an external reset pulse can be applied. Upon release of the initial reset command, the oscillator will oscillate with a frequency determined by the external RC network. The 16-stage counter divides the oscillator frequency (f
    with the n
    stage frequency being f
    /2
    .
    • Available Outputs 2

    • 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
    • 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 2
    • 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 = V
    • )
    • 8.5 Vdc to 18 Vdc with Auto Reset Enabled (Pin 5 = V
    • )
    • Pb-Free Packages are Available*
