The 74AHCT164D14 is a logic-shift register and is part of a series of High-Speed CMOS Logic Integrated Circuits developed by Texas Instruments Incorporation (TI). It is used in a variety of application fields ranging from communications to industrial control systems.

This 8-bit shift register is a member of the Texas Instruments Extended Logic Family, which provides quick and cost-effective solutions for many digital design tasks. The device is designed for higher operating frequency, lower active power dissipation, better output drive capability, and more immunity to noise. It has a relatively low input current of ≤ 5 µA compared to ≤ 10 µA for normal LS families. It also offers an improved propagation delay of 7.5ns compared to 12.5ns for the regular LS devices.

The 74AHCT164D14 consists of a D-type flip-flop that is triggered by a rising edge of the Clock input as data is shifted in at the Data input pin. The data is shifted in the right direction once the ‘mode’ is enabled by the MR line. Operating at a low voltage of 2.5V, this device is well suited for applications with the presence of long wires and high noise environments. With an improved active power dissipation of 0.3mW and static power dissipation of 0.1mW, this device is quite suitable for battery-powered systems as well.

The Active Power Dissipation (APD) of the 74AHCT164D14 is 0.3mW, while the max power dissipation (MPD) is 6.51mW. It operates within a temperature range from -65°C to 125°C and it has a maximum clock frequency of 20 MHz. This device comes with an operating current of 0.3mA and a standby current of 0.1 mA. It has a maximum propagation delay of 7.5ns, a voltage supply range of 1.4V to 3.6V, and is available in 16-pin SOIC package.

The 74AHCT164D14 logic-shift register is a great option for engineers who are looking to design systems with higher speed, better accuracy and greater power efficiency. It is useful in a variety of applications such as communications, industrial control systems and embedded control systems with its high frequency, low active power dissipation and better output drive capability. Furthermore, with a wide voltage and temperature range, this device can be used in many different environments.
