CD74ACT164M is a logic - shift register, which consists of an 8-stage parallel-in, serial-out shift register. This shift register can be used to store and transfer data serially. It is designed to work in high speed and low power applications such as embedded control, instrumentation, communication systems, and networking. Its 8-bit shift register offers up to 128 bits of data storage capacity, while its four selectable operating frequencies allow it to achieve speeds up to 400 MHz.

The CD74ACT164M, which is typically used as a general input/output (I/O) shift register, has seven data inputs (D0 through D6) and two clock inputs (CPA and CPB). The device is controlled by the two clock inputs, which can be used to output data serially, as well as to shift data from the shift register. In addition, the CD74ACT164M has one control input (CinQ) and one output enable pin (OE) that can be used to control data output from the device. The device is able to operate with a wide range of operating voltages, from 1.65V to 5.5V.

The working principle of the CD74ACT164M is quite simple. When the clock signal (CPA or CPB) is asserted and the CinQ signal is asserted, the data present at the data inputs is loaded into the shift register. When the clock signal is de-asserted, the data is shifted to the right and available at the output pin. If the output enable pin (OE) is high, data will be shifted out continuously until CinQ signal goes low. Then, the shift register will be reset and data will cease to be shifted out.

The CD74ACT164M has multiple uses in various applications such as data transmission, data storage, signal routing, signal amplification, and signal conversion. It can be used in motor control systems and industrial automation systems as a logic device for scene recognition, data loggers, embedded controllers, and sensors. It can also be used in clock generators for data synchronization and communication. The device can also be used in audio and video signal processing applications such as video decoders, video encoders, data compressing and decompressing systems.

Overall, the CD74ACT164M is a low-power, high-speed, 8-stage parallel-in, serial-out shift register that can be used to store and transfer data in various applications. It is a highly-versatile device that can be used as a general input/output shift register. The device offers up to 128 bits of data storage capacity and can operate in a wide range of operating voltages, from 1.65V to 5.5V. The device is commonly used in motor control systems, industrial automation systems, clock generators, audio/video signal processing applications, and embedded control systems.
