Additional Information

  • Summary
  • Tech Specs
  • Reviews
The NTE4541B (14−Lead DIP) and NTE4541BT (SOIC−14) programmable timers consist of a 10−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 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. For 16−stage counter divides the oscillator frequency (fOSC) with the nth stage frequency being fOSC/2n.
  • Available outputs 28, 210, 213, or 216
  • Increments on positive edge clock transitions
  • Low symmetrical output resistance (typically 10Ω at 15VDC)
  • Built−in low power RC oscillator
  • ±2% accuracy over temperature range and ±10% supply and ±3% over processing at < 10kHz
  • Oscillator frequency range DC to 100kHz
  • Oscillator may be bypassed if external clock is available (apply external clock to pin3)
  • Automatic reset initializes all counters when power turned on
  • Limits − VDD from 8.5VDC to 18VDC when enabled
  • 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
  • Supply voltage range = 3VDC to 18VDC
