ON Semiconductor MC74HC164AD - 8-Bit Serial-Input/Parallel-Output Shift Register

The MC74HC164AD from ON Semiconductor is a high-performance, 8-bit serial-input/parallel-output shift register designed for use in a wide range of digital applications. This integrated circuit is part of ON Semiconductor's HC family, which is well-known for its high noise immunity and low power consumption, making it suitable for interfacing with CMOS logic levels.

This device features two serial data inputs (A and B), eight parallel data outputs (Q0 to Q7), a clock input, and a reset input. The serial inputs allow the MC74HC164AD to receive data one bit at a time, while the parallel outputs provide the capability to output the stored data simultaneously in an 8-bit format. The clock input is used to synchronize the data entry, and the reset input clears the internal registers, setting all output pins to a low state.

Constructed with silicon gate CMOS technology, the MC74HC164AD offers significant advantages, including the ability to operate at a wide voltage range from 2V to 6V. This flexibility in operating voltage makes it compatible with a variety of logic families and ensures stable performance across different power supply conditions. Additionally, the device has a high output drive capability, which allows it to drive multiple loads without the need for additional buffering.

The MC74HC164AD is typically utilized in applications that require the conversion of serial data to parallel format, such as in microcontroller interfaces, digital signal processing, data acquisition systems, and many other digital communication systems. Its small footprint and the convenience of having a serial-to-parallel conversion mechanism make it an ideal choice for space-constrained applications.

ON Semiconductor provides this shift register in a surface-mount SOIC-14 package, ensuring ease of integration into printed circuit boards. The MC74HC164AD is also characterized for operation from -55°C to +125°C, guaranteeing reliable performance even in extreme environmental conditions.

With its robust design, compatibility with various logic levels, and ease of use, the MC74HC164AD shift register from ON Semiconductor is a versatile component that can enhance the functionality of a wide array of digital systems.
