Logic - Shift Registers

Shift registers are devices that transfer data from one location to another. The 74LV595DB,112 is an 8-bit parallel-in to serial-out shift register, which can store up to 8 bits of data from an 8-bit input. It does this by transferring the data through a series of registers, which are connected together in a daisy chain fashion.

The 74LV595DB,112 is well suited for use in multiple applications for applications that require an 8-bit shift register to transfer data from one location to another rapidly. For example, in digital control systems that require synchronizing data from an input source to the system. Also, it is well suited for use in data transfer devices such as keyboards and displays.

The basic principle of operation of the 74LV595DB,112 is based on the clocking mechanism. It is triggered by a clock signal which can either be a positive-going or negative-going pulse. The clock signal is applied to the ‘SH/LD’ pin, leading to the data being transferred to the output register. During a positive-going clock pulse, the data from the input register is transferred to the output register, while during a negative-going pulse, the data from the output register is transferred to the input register.

The circuitry of the 74LV595DB,112 is quite simple. It consists of 8 registers, which are connected in a daisy chain fashion in order to transfer the data from the input register to the output register. There are also two control signals, namely, the clock signal and the ‘SH/LD’ pin. The clock signal is used to initiate the clocking process and the ‘SH/LD’ pin is used to select whether the data should be transferred from the input or output register.

Applications include use within micro-controllers and digital control systems, keyboard and display controllers, chip selectors, and other complex digital systems. It is often used in digital electronics such as clocks, calculators, cameras, cellular phones, and other household devices.

The 74LV595DB,112 is straightforward and cost effective to use when compared to alternative shift register ICs. It provides excellent performance in data transfer, and requires only a simple clock and ‘SH/LD’ signal to operate. This makes it ideal for applications that require rapid data transfer between two devices, or for applications that require synchronizing data from an input source.
