Product Overview: MC74HC164AFL1 from ON Semiconductor

The MC74HC164AFL1 is a high-speed, integrated circuit from ON Semiconductor designed for digital applications. This 8-bit serial-input/parallel-output shift register is a member of the high-performance HC series and is fabricated with silicon gate CMOS technology. It offers a blend of high density, low power consumption, and speed that is characteristic of CMOS integrated circuits, making it a versatile choice for a wide range of digital applications.

This shift register has two serial data inputs (A and B), which allow it to operate in either a single-input mode or in a parallel-input mode when both inputs are used together. The eight parallel outputs (Q0 to Q7) provide the shifted data. The device features a common clock input (CP) and an asynchronous master reset input (MR) that clears the register, setting all outputs to a low level when applied with a high signal.

The MC74HC164AFL1 operates over a broad voltage range from 2V to 6V and offers significant advantages in power efficiency. The low power consumption is especially beneficial in battery-powered devices, where extending operational life is crucial. Additionally, the device's high noise immunity and low power dissipation make it a reliable choice for noisy or power-sensitive environments.

With its fast propagation delays and high current drive capability, the MC74HC164AFL1 can drive up to 10 LS-TTL loads, which makes it highly compatible with existing TTL logic, thereby simplifying the integration into mixed-technology systems. The device is also characterized for operation from -55°C to 125°C, ensuring reliable performance across a wide temperature range, suitable for industrial and automotive applications.

ON Semiconductor's commitment to quality ensures that the MC74HC164AFL1 meets the stringent requirements needed for use in critical systems. It is typically packaged in a lead-free, 16-pin SOIC package, which is designed for optimal space-saving on printed circuit boards. Whether used in microprocessor expansion, digital signal processing, or general-purpose logic applications, this shift register provides a reliable solution for data manipulation and signal processing tasks.
