74HC(T)20

Dual 4-input NAND gate

The 74HC20; 74HCT20 is a dual 4-input NAND gate. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Features

  • Complies with JEDEC standard JESD7A
  • Low-power dissipation
  • Input levels:
    • For 74HC20: CMOS level
    • For 74HCT20: TTL level
  • ESD protection:
    • HBM JESD22-A114F exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
  • Multiple package options
  • Specified from -40 °C to +80 °C and from -40 °C to +125 °C
