4015 IC Shift Register Serial to parallel PDIP-16 Original
The CD4015B is a monolithic CMOS integrated circuit that functions as a dual 4-bit static shift register. Its primary role is to convert serial data into parallel data, operating as a serial-in, parallel-out (SIPO) register. The device is constructed using complementary MOS technology, which provides it with the classic benefits of very low power consumption and a wide operating voltage range. This makes it a versatile and robust building block for various digital logic systems, capable of interfacing with both CMOS and TTL logic families when operated at a suitable voltage.
The IC contains two identical and completely independent shift registers on a single chip. Each register has its own dedicated data input, clock input, and a master reset input, allowing for flexible and separate control. Data presented at the serial input is shifted into the register on the low-to-high transition of the clock pulse. The master reset input, when set to a high logic level, asynchronously clears all stages of its respective register, forcing all outputs to a low state, regardless of the clock or data input conditions.
Each of the four stages in a register is represented by a Q output, providing parallel access to the shifted data. The data bit moves from one stage to the next with each clock pulse, effectively creating a delay line or a means to hold multiple bits of data. This parallel output structure is ideal for tasks like driving multiple outputs from a single serial data line, such as illuminating LEDs or controlling other digital loads, thereby reducing the number of microcontroller I/O pins required in a system.
