NTE4541B and NTE4541BT  
Integrated Circuit  
CMOS, Programmable Timer  
Description:  
The NTE4541B (14Lead DIP) and NTE4541BT (SOIC14) programmable timers consist of a  
10stage 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 de-  
termined by the external RC network. For 16stage counter divides the oscillator frequency (fOSC  
)
with the nth stage frequency being fOSC/2n.  
Features:  
D Available Outputs 28, 210, 213, or 216  
D Increments on Positive Edge Clock Transitions  
D Low Symmetrical Output Resistance (Typically 10Ω at 15Vdc)  
D BuiltIn Low Power RC Oscillatior  
( 2% Accuracy over Temperature Range and 10% Supply and  
3% over Processing at < 10kHz)  
D Oscillator Frequency Range DC to 100kHz  
D Oscillator may be Bypassed if External Clock is Available (Apply External Clock to Pin3)  
D Automatic Reset Initializes All Counters when Power Turn On  
(Limits VDD from 8.5Vdc to 18Vdc when Enabled)  
D External Master Reset Totally Independent of Automatic Reset Operation  
D Operates as 2n Frequency Divider or Single Transition Timer  
D Q/Q Select Provides Output Logic Level Flexibility  
D Reset (Auto or Master) Disables Oscillator during Resetting to Provide No Active Power Dissipation  
D Clock Conditioning Circuit Permits Operation with Very Slow Clock Rise and Fall Times  
D Supply Voltage Range = 3Vdc to 18Vdc
