ON Semiconductor MC74HC165ADR2G Parallel-Load 8-Bit Shift Register

The MC74HC165ADR2G is a high-performance, 8-bit shift register designed by ON Semiconductor, a leading innovator in energy-efficient electronics. This integrated circuit is a crucial component in digital systems where parallel data acquisition and serial data output are required. It is particularly useful in expanding the input capability of a microprocessor or microcontroller by converting parallel data to serial format.

Engineered with advanced silicon-gate CMOS technology, the MC74HC165ADR2G offers a robust combination of high speed, low power consumption, and enhanced durability. It operates with a wide range of supply voltages from 2V to 6V, which makes it suitable for various applications, from battery-operated devices to industrial control systems.

The device features an 8-bit serial shift register with a direct clear function (CLR), two clock inputs (CP and CE), and a serial output function (QH). The parallel inputs (A to H) allow for the simultaneous loading of data, which can then be serially shifted out through the QH output upon application of the clock signal. The two clock inputs allow for either positive-edge triggering (CP) or negative-edge triggering (CE), providing additional flexibility in system design.

Additionally, the MC74HC165ADR2G supports serial-to-serial operation by cascading multiple devices, thanks to the serial input (SER) and output (QH) pins. This feature enables the creation of shift registers of virtually any length, accommodating a wide range of data processing requirements.

The device is provided in a compact SOIC-16 package, ensuring a minimal footprint on printed circuit boards, which is essential for space-constrained applications. With its industry-standard pin configuration, the MC74HC165ADR2G ensures easy integration into existing and new designs, supporting a seamless design experience for engineers and technicians.

In summary, the ON Semiconductor MC74HC165ADR2G is a versatile and reliable component that is ideal for applications requiring the conversion of parallel data to serial data. Its high-speed operation, low power consumption, and flexible design make it an excellent choice for a wide range of digital systems.
