ON Semiconductor MC74HC164ADG

The MC74HC164ADG is a high-performance, 8-bit serial-in/parallel-out shift register produced by ON Semiconductor, a renowned leader in the semiconductor industry. This integrated circuit (IC) is designed to interface with standard logic families and is fabricated with silicon gate CMOS technology, ensuring a reliable and efficient performance.

This device features two serial data inputs (A and B), eight parallel outputs (Q1 to Q8), a clock input, and a clear input. The MC74HC164ADG operates over a wide voltage range from 2V to 6V, making it versatile for various applications. The low power consumption and high noise immunity characteristic of CMOS technology are inherent in this device, making it suitable for use in battery-operated and noise-sensitive electronic systems.

The serial inputs allow for easy expansion by simply connecting the Q7' output to the A and B inputs of a subsequent register. The clock input is responsible for synchronizing the data transfer, which occurs on the rising edge of the clock pulse. The clear input, when taken low, resets the entire shift register, providing an asynchronous clear function that enhances the flexibility of the device.

The MC74HC164ADG is available in a narrow 14-pin SOIC package, which is ideal for space-constrained applications. It is commonly used in a variety of digital systems such as computer peripherals, instrumentation, and control systems, where it allows for the conversion of serial data to parallel output data. This can be particularly useful for expanding the number of outputs from a microcontroller or other digital processor with a limited number of I/O pins.

ON Semiconductor's commitment to quality ensures that the MC74HC164ADG meets stringent standards, providing a reliable solution for designers looking to implement shift register functions in their digital logic designs. With its robust performance and ON Semiconductor's support, the MC74HC164ADG is an excellent choice for your digital circuit needs.
