Introduction to SN74LS164NSR

The SN74LS164NSR is an 8-bit shift register, a type of logic circuit used to store and shift around digital information. It is an integrated circuit (IC) manufactured by Texas Instruments and designed to work in conjunction with TTL (Transistor-Transistor Logic).It is a very popular device, commonly used for handling data in mission-critical applications where reliability and speed of operation are paramount. Shift registers are versatile components, often used for a wide range of tasks from data conversion to address generation.

SN74LS164NSR Application Field

The SN74LS164NSR is primarily used to store and shift around digital data, and it is ideal for applications where speed, reliability and accuracy are of paramount importance. It can be used in circuit designs that involve the transfer of serial data to parallel data or parallel data to serial data.Common applications of the SN74LS164NSR include data conversion between serial and parallel formats, display driver and address generator circuitry, digital-to-analog and analog-to-digital converters, and as part of a memory address decoder/generator in computer systems.

SN74LS164NSR Working Principle

The SN74LS164NSR is an 8-bit shift register that is composed of two 4-bit shift registers separated by an 8-bit latch. The device works by shifting the data stored in the 8-bit latch either to the parallel outputs, or to the 4-bit shift register on the left side of the latch, with each pulse from the clock input.Once a clock pulse has been given, the data in the latch is shifted out of the device, and the next bit of data is loaded into the latch from the data input. By providing successive clock pulses, the data stored in the latch can be shifted out of the device, one bit at a time.The SN74LS164NSR can be used to convert parallel data to serial data, or to shift serial data in either left or right directions. Additionally, the device can be used to generate and store address information, to provide digital-to-analog and analog-to-digital conversion, and to provide digital output from a multiplexed data source.

Conclusion

The SN74LS164NSR is an 8-bit shift register manufactured by Texas Instruments that is designed to work with TTL (Transistor-Transistor Logic). It is ideal for applications where speed, reliability and accuracy are of paramount importance and can be used for a wide range of tasks from data conversion to address generation. The device works by shifting the data stored in an 8-bit latch either to the parallel outputs, or to the 4-bit shift register on the left, with each pulse from the clock input. By providing successive clock pulses, the data stored in the latch can be shifted out of the device, one bit at a time.
