Gates and Inverters

quad NORSchmitt triggerCMOS logicWQFN-142 V to 6 V

SN74HCS02BQAR is a 14-pin WQFN quad 2-input NOR gate for 2 V to 6 V logic systems where Schmitt-trigger inputs help tolerate slow or noisy signals.

Best for

  • Slow or noisy digital input conditioning
  • SR latch circuits
  • Tamper or alarm detection logic

Avoid if

  • A non-NOR logic function is required
  • Supply voltage is outside 2 V to 6 V
  • The design cannot support a 0.5 mm-pitch WQFN footprint

Check before use

  • Schmitt-trigger threshold range at the actual VCC
  • Output drive and load capacitance
  • Unused input termination
  • WQFN thermal-pad connection choice
