The term Logic - Shift Registers refers to a family of digital logic gates used in digital systems. The devices are integrated into digital applications in order to control the flow of data or enable/disable certain devices. Several common shift register types include Binary (BRS), Universal (UDL), Dual-Rail (DRL), and Multi-Input (MIS). Each of these applications utilizes various gate types, allowing for efficient data movement.
Among the most common shift register type is the CD74HC166MT, a 4-bit parallel-in parallel-out shift register designed for applications like multiplexing, frequency division, pulse width modulation, counter division, and encoder division. The device provides a byte-wide data path and is highly flexible for different kinds of high-speed logic applications.
The core of the CD74HC166MT is made up of four individual stages, each stage with one data input, two control inputs, and one data output. Each stage in the shift register has two control inputs, a clock (CLK) and a load (LD). The CLK is used to initiate data movements while the LD input is used as a load reset or disabled signal.
The data input is a single line that can accept either a logic high or logic low level. In parallel, four input lines can be used to input data. Data can be entered serially, such as in a powerful universal asynchronous receiver/transmitter (UART) type logic, or in parallel, such as when a large number of inputs needs to be processed quickly. The data output of each stage, taken from the highlighted QR switch, serves as the output of the stage.
The CLK input of each stage is used to shift the data from one stage to another. A high CLK level indicates that the data should shift and a low CLK level indicates that the data should remain stationary. Similarly, the LD input will reset all the stages when it is set to a logic high level and allow for the data to move freely when it is set to a logic low level. When both the CLK and the LD are high, all the stages are reset, thus making them available for new and different data inputs.
When an input is applied, it passes through the stages, one bit at a time, and the output comes out of the last bit in the shift register. The data is shifted in or out of the register, depending upon the signals on the CLK and LD pins. In multiplexing applications, the shift register can be used to sample different data inputs and allow them to output on a single line. In frequency division, the shift register is used to divide a high-frequency data signal.
The CD74HC166MT is designed to handle data throughput up to 50 MHz. This allows for high-speed data processing and is ideal for applications that require highly flexible and efficient data movement. The device can be used in a wide range of applications, from consumer electronics to automotive electronics, making it a must-have for new products that require fast, efficient data manipulation.
