74HC3G34; 74HCT3G34

Triple buffer gate

The 74HC3G34; 74HCT3G34 is a triple buffer. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Features and benefits

  • Wide supply voltage range from 2.0 V to 6.0 V
  • Input levels:
    • For 74HC3G34: CMOS level
    • For 74HCT3G34: TTL level
  • Complies with JEDEC standard no. 7 A
  • Symmetrical output impedance
  • High noise immunity
  • Low-power dissipation
  • Balanced propagation delays
  • Multiple package options
  • ESD protection:
    • HBM JESD22-A114E exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
  • Specified from -40 °C to +85 °C and -40 °C to +125 °C
