ON Semiconductor MM74HC164MTC: 8-Bit Serial-In Parallel-Out Shift Register

The MM74HC164MTC from ON Semiconductor is a high-performance CMOS 8-bit serial-in/parallel-out shift register designed to offer a perfect blend of speed, power efficiency, and robust functionality. This integrated circuit (IC) is a versatile component that is commonly used in a wide range of digital applications such as data processing, communication systems, and control interfaces.

With its advanced silicon-gate CMOS technology, the MM74HC164MTC ensures reduced power consumption without sacrificing speed. The device operates over a broad voltage range of 2V to 6V and provides typical clock frequencies at 10MHz when powered at 5V. This makes it a suitable choice for battery-operated devices as well as high-speed systems.

The MM74HC164MTC features an 8-bit serial input (DIN) and an 8-bit parallel output (Q0 to Q7) configuration. The serial data is entered into the shift register on the rising edge of the clock signal (CP), allowing for synchronous data transfer. The outputs change state on the clock's rising edge, providing a reliable and predictable output response for connected circuitry.

This device also incorporates two serial data inputs (A and B), which can be used individually or tied together for parallel processing. The clear function (MR) enables the user to reset the internal registers, setting all outputs to a low state, which is especially useful in initializing or resetting systems during power-up or after an error condition.

The MM74HC164MTC is housed in a compact TSSOP-14 package, making it an excellent choice for space-constrained applications. Its pin configuration is optimized for easy PCB layout and interfacing with other components. Furthermore, the IC is characterized for operation from -40°C to +85°C, ensuring reliable performance in a wide range of environmental conditions.

In summary, the MM74HC164MTC from ON Semiconductor is a reliable and efficient solution for applications requiring serial-to-parallel data conversion. Its low power consumption, high-speed operation, and robust feature set make it an ideal choice for designers looking to enhance their digital systems.
