Gates and Inverters

dual NAND4-input NANDSchmitt triggerCMOS logicSOIC-142 V to 6 V

SN74HCS20DR is a dual 4-input NAND gate with Schmitt-trigger inputs for 2 V to 6 V CMOS logic designs requiring tolerance of slow or noisy signals.

Best for

  • Slow or noisy digital input signals
  • Simple 4-input NAND logic
  • Alarm, tamper, and latch logic

Avoid if

  • The application requires a supply outside 2 V to 6 V
  • A different logic function or open-drain output is required

Check before use

  • Verify thresholds and hysteresis at the actual VCC
  • Verify output load current and total package current
  • Use local VCC-to-GND decoupling
