Application Notes

  • Digital PLL Design Using the SN54/74LS297 (Rev. B)
    PDF, 597 Kb, Revision: B, File published: Mar 1, 1997
    The SN54/74LS297 performs a first-order PLL function with a high degree of accuracy and a minimum of external components. Features include entirely digital design, accuracy with varying temperatures and voltages, digitally programmable bandwidth and center frequency, narrow bandwidth, ripple cancellation, and cascading capabilities for high-order loops. This document provides a device description,
  • Designing with the SN54/74LS123 (Rev. A)
    PDF, 118 Kb, Revision: A, File published: Mar 1, 1997
    The Texas Instruments (TI) SN54/74LS123 dual retriggerable monostable multivibrator is a one-shot device capable of verylong output pulses and up to 100% duty cycle. The ?LS123 also features dc triggering from gated low-level active A andhigh-level active B inputs and provides a clear input that terminates the output pulse of any predetermined time independentof timing components R ext and
