11.1 Layout Guidelines

To ensure reliability of the device, TI recommends following common printed-circuit board layout guidelines.

  • Bypass capacitors should be used on power supplies.
  • Short trace lengths should be used to avoid excessive loading
  • PCB signal trace-lengths must be kept short enough so that the round-trip delay of any reflection is less than the one shot duration, approximately 30 ns, ensuring that any reflection encounters low impedance at the source driver
  • With very heavy capacitive loads, the one-shot can time-out before the signal is driven fully to the positive rail, so it is recommended that this lumped-load capacitance be considered and kept below 50 pF to avoid O.S. retriggering, bus contention, output signal oscillations, or other adverse system-level affects.
