74HC2G34; 74HCT2G34

Dual buffer gate

The 74HC2G34; 74HCT2G34 is a dual buffer. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

特性

  • Wide supply voltage range from 2.0 V to 6.0 V

  • High noise immunity

  • CMOS low power dissipation

  • Balanced propagation delays

  • Unlimited input rise and fall times

  • Input levels:

    • For 74HC2G34: CMOS level

    • For 74HCT2G34: TTL level

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

  • Complies with JEDEC standards

    • JESD8C (2.7 V to 3.6 V)

    • JESD7A (2.0 V to 6.0 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
