ON Semiconductor MC74HC164ADR2
The ON Semiconductor MC74HC164ADR2 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 (IC) is part of the high-speed CMOS HC family, and it is known for its robustness and reliability. The MC74HC164ADR2 features two serial data inputs (A and B), eight parallel outputs (Q0 to Q7), a clock input, and a clear input to reset the register.
The device operates with a supply voltage ranging from 2V to 6V, making it suitable for interfacing with both TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) logic levels. Its low power consumption and wide operating voltage range make it an excellent choice for battery-powered and low-power systems.
The MC74HC164ADR2 comes in a compact SOIC-14 (Small Outline Integrated Circuit) package, which is ideal for space-constrained applications. Its small footprint and surface-mount design allow for efficient use of PCB (Printed Circuit Board) space, which is critical in today's miniature electronic devices.
One of the key features of the MC74HC164ADR2 is its ability to directly drive LEDs and other displays, thanks to its high current outputs. This makes it an excellent choice for creating visual indicators in consumer electronics, industrial control panels, and automotive dashboards. Its fast data transfer rate also enables it to perform well in high-speed data logging and communication systems.
The shift register is easy to use, with a simple serial data input mechanism that allows multiple MC74HC164ADR2 devices to be cascaded, increasing the number of parallel outputs without increasing the number of control signals. This cascading capability is particularly useful for applications requiring extended data storage or manipulation, such as in digital signal processing or computer peripherals.
In summary, the ON Semiconductor MC74HC164ADR2 is a versatile and reliable component that offers a blend of performance, power efficiency, and ease of integration, making it a go-to choice for designers looking to implement serial-to-parallel data conversion in their digital systems.
