Overview
The CD4020BNSR is a 14-stage ripple-carry binary counter produced by Texas Instruments. This component is part of the CD4000 series of CMOS logic integrated circuits. It is designed for medium-speed operation and features fully static operation, making it suitable for a variety of digital circuit applications. The counter stages are master-slave flip-flops, and the state of the counter advances one count on the negative transition of each input pulse. A high level on the RESET line resets the counter to its all zeros state. The CD4020BNSR is available in a 16-lead small-outline package (NSR suffix), ensuring compact and efficient integration into modern electronic designs.
