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
