Product Overview: 74AHC164D

The 74AHC164D is a high-speed Si-gate CMOS device designed and manufactured by NXP Semiconductors. This integrated circuit is a part of the 74AHC series, known for its robust performance and compatibility with TTL levels. The 74AHC164D is an 8-bit serial-in, parallel-out shift register that allows the conversion of serial input data into parallel output format, offering a practical solution for expanding the data handling capability of a microcontroller or processor with a limited number of I/O lines.

The device features two serial data inputs (A and B), eight parallel outputs (Q0 to Q7), a clock input, and a clear input. The clear input allows for the immediate clearing of the internal registers, resetting the output pins to a low state. The clock input governs the data transfer on the rising edge, ensuring precise timing and synchronization within digital circuits.

With its wide operating voltage range of 2.0V to 5.5V, the 74AHC164D is versatile and suitable for interfacing with both 3.3V and 5V systems. This makes it an excellent choice for a variety of applications, including computing, consumer electronics, and embedded systems.

The device is provided in a small-outline package (SO) with 14 pins, identified as SO14 in NXP's product catalog. This compact form factor ensures minimal footprint on printed circuit boards (PCBs), making it an ideal component for space-constrained applications. Additionally, the 74AHC164D boasts low power consumption and high noise immunity, characteristic of the advanced CMOS technology used in its construction.

Key features of the 74AHC164D include:

• High-speed operation
• Compatibility with TTL levels
• Low power dissipation
• Wide operating voltage range
• High noise immunity
• 14-pin small-outline package

In summary, the NXP 74AHC164D shift register is a reliable and efficient solution for serial-to-parallel data conversion in digital systems. Its high-speed operation, wide voltage compatibility, and small package size make it a versatile component suited for a broad range of applications.
