Diodes Incorporated 74AHC164D14: An Overview

The 74AHC164D14 from Diodes Incorporated is a high-speed, 8-bit serial-in/parallel-out shift register designed to provide efficient and reliable performance in a wide range of digital applications. This integrated circuit is part of the 74AHC family, which is renowned for its high-speed CMOS technology, offering a perfect balance between speed and power consumption.

The device features two serial data inputs (A and B) for parallel or serial entry, eight parallel outputs (Q0 to Q7), and a single clock input. Data is entered serially through either input A or B and is shifted out in parallel format on the rising edge of the clock pulse. This makes the 74AHC164D14 an ideal choice for applications requiring the conversion of serial data to parallel data, such as in microcontroller interfaces, digital signal processing, and data communication systems.

One of the key advantages of the 74AHC164D14 is its wide operating voltage range of 2V to 5.5V, which allows it to be used in various logic level environments. Additionally, the device boasts a low power consumption with a typical ICC of only 20µA, making it suitable for battery-operated and power-sensitive applications.

The 74AHC164D14 comes in a 14-pin SOIC package, which is compact and suitable for space-constrained applications. Its robust design ensures high durability and reliability, with protection against over-temperature and electrostatic discharge (ESD). This makes it a solid choice for industrial, consumer electronics, and automotive markets, where consistent performance and longevity are crucial.

Key features of the 74AHC164D14 include:

• 8-bit serial-in, parallel-out shift register
• Wide operating voltage range: 2V to 5.5V
• High noise immunity
• Low power dissipation
• 14-pin SOIC package for compact footprint
• Compliant with JEDEC standard no. 7A
• ESD protection exceeds JESD 22

In summary, the 74AHC164D14 from Diodes Incorporated is a versatile and efficient solution for serial-to-parallel data conversion applications, offering a blend of high speed, low power consumption, and reliable performance in a compact package.
