HEF4014BT – PHILIPS

Overview

The Nexperia HEF4014BT is an 8-bit synchronous, parallel-access shift register designed for serial-to-parallel data conversion and general-purpose data manipulation. Its key operational characteristic is the ability to capture parallel data inputs synchronously with a clock edge and then shift this data out serially. A critical design consideration when utilizing CMOS logic families like the HEF4000 series, particularly in high-speed applications, is the potential for input voltage overshoot and undershoot exceeding the supply rails, which can lead to device latch-up. Careful impedance matching and the use of appropriate series resistors on input lines are therefore paramount to ensure robust operation and prevent damage.
