Texas Instruments SN74HCS20/SN74HCS20-Q1 Dual 4-Input NAND Gate

Texas Instruments SN74HCS20/SN74HCS20-Q1 Dual 4-Input NAND Gate contains two independent 4-input NAND gates with Schmitt-trigger inputs. Each gate performs the Boolean function Y = A ● B ● C ● D in positive logic. The Texas Instruments SN74HCS20-Q1 devices are AEC-Q100 qualified for automotive applications.

Features

  • 2V to 6V wide operating voltage range
  • Low power consumption
    • Typical ICC of 100nA
    • Typical input leakage current of ±100nA
  • Schmitt-trigger inputs allow for slow or noisy input signals
  • ±7.8mA output drive at 5V
  • Extended ambient temperature range of -40°C to +125°C, TA

Applications

  • Alarm/tamper detect circuit
  • S-R latch
