Programmable Timer
The MC14541B programmable timer consists of a 16stage binary
counter, an integrated oscillator for use with an external capacitor and
two resistors, an automatic poweron reset circuit, and output control
logic.
Timing is initialized by turning on power, whereupon the poweron
reset is enabled and initializes the counter, within the specified VDD
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
16stage counter divides the oscillator frequency (fosc) with the nth
stage frequency being fosc/2n.
Features
Available Outputs 28, 210, 213 or 216
Increments on Positive Edge Clock Transitions
Builtin 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/Q Select Provides Output Logic Level Flexibility
Reset (auto or master) Disables Oscillator During Resetting to
Provide No Active Power Dissipation
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
Supply Voltage Range = Disabled (Pin 5 = VDD)
Supply Voltage Range = 8.5 Vdc to 18 Vdc with Auto Reset
Supply Voltage Range = Enabled (Pin 5 = VSS)
PbFree Packages are Available
