SN74LS164J 8-Bit Parallel-Out Serial Shift Registers

The SN74LS164J from Texas Instruments is a high-performance, 8-bit serial-in, parallel-out shift register designed for use in a wide range of digital applications. This integrated circuit is part of the 74LS logic family, known for its low power consumption and high-speed operation. The SN74LS164J is particularly useful in systems where it is necessary to expand the number of outputs without increasing the number of I/O pins on the microcontroller or processor.

Constructed with bipolar silicon technology, the SN74LS164J features two serial data inputs (A and B), eight parallel outputs (Q0 to Q7), a clear input, and a clock input. The clear input allows for the synchronous reset of the register, setting all outputs to a low level, while the clock input governs the timing of data shifting through the register.

One of the key advantages of the SN74LS164J is its ability to shift data into the register on the rising edge of the clock signal, allowing for precise timing and control in high-speed digital circuits. The device can be used in a variety of applications, such as data acquisition systems, digital displays, and any circuit requiring the conversion of serial data to parallel form.

This shift register is packaged in a standard 14-pin J-lead ceramic package, which offers robust physical protection and reliable performance even in harsh environmental conditions. The SN74LS164J operates over a wide range of voltages, typically from 4.75V to 5.25V, and provides typical power dissipation of 80mW, making it an energy-efficient choice for portable and battery-powered applications.

With its straightforward interface and ease of use, the SN74LS164J is an excellent choice for designers looking to implement serial-to-parallel data conversion with minimal signal delay and high data throughput. Texas Instruments provides comprehensive technical support, including detailed datasheets, application notes, and design resources to assist in the integration of the SN74LS164J into a wide array of electronic projects and products.
