Though HEF4000B series is one of the oldest CMOS logic families around, it is still frequently used in new designs because of its ease of design-in, wide operating supply range (3 V to 15 V), excellent noise immunity, and low power consumption. All of the standard functions are available, plus more specialized functions such as IEEE bus interfaces and PLL frequency synthesizers.

HEC variants are also available see: HEC variants overview

Features and benefits

  • Large supply range 3 V to 15 V
  • Standard operating temperature range is -40 °C to 85 °C (HEF) with an extended -55 °C to 125 °C (HEC) available
  • New designs with 8- and 12-stage shift registers capable of driving 20mA loads (HEF4794B and HEF4894B)
  • Virtually all parts available in DIL and SO packages

Applications

  • Medical equipment
  • General industrial
  • Consumer electronics
  • Toys and games
  • Glue logic applications
