Logic Chips are digital integrated circuits that perform arithmetic, logical operations and signal control. Their core functions include AND/OR/NOT logic operations, data selection and comparison, timing control, flip-flop and register storage. Common types include general-purpose logic gates (74 series, CD4000 series), microcontrollers (MCUs), programmable logic devices (FPGA/CPLD) and special-purpose logic chips such as counters and decoders. They are widely used in communications, industrial control, consumer electronics, automotive electronics and other fields, serving as the core computing and control units of digital systems to support logical decision-making and function implementation of equipment.
