74HC2G02; 74HCT2G02

Dual 2-input NOR gate

The 74HC2G02; 74HCT2G02 is a dual 2-input NOR gate. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

The 74HCT2G02 features reduced input threshold levels to allow interfacing to TTL logic levels.

Features and benefits

  • Wide supply voltage range from 2.0 V to 6.0 V

  • Input levels:

    • For 74HC2G02: CMOS level

    • For 74HCT2G02: TTL level

  • CMOS low power dissipation

  • High noise immunity

  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

  • Complies with JEDEC standard no. 7A (4.5 V to 5.5 V)

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Specified from -40 °C to +85 °C and -40 °C to +125 °C
