Overview
The HEF4015BT,653 is a dual edge-triggered 4-bit static shift register (serial-to-parallel converter) produced by Nexperia USA Inc. This component is part of the HEF4000 series and is designed for a wide range of applications, including automotive, industrial, and consumer electronics. Each shift register features a serial data input (nD), a clock input (nCP), four fully buffered parallel outputs (Q0 to Q3), and an overriding asynchronous master reset input (nMR). The device operates over a recommended VDD power supply range of 3 V to 15 V and is suitable for use over the full industrial temperature range of -40°C to +85°C.
