Product Overview: 74AHCT164PW by NXP Semiconductors

The 74AHCT164PW is a high-speed Si-gate CMOS device designed and manufactured by NXP Semiconductors. It is an 8-bit serial-in, parallel-out shift register that captures the values of 8 data inputs in a sequential manner and provides parallel output. This shift register is particularly suitable for a wide range of applications, including digital signal processing, data management, and circuit interface tasks.

Featuring a compact TSSOP 14 (Thin Shrink Small Outline Package) form factor, the 74AHCT164PW is designed to occupy minimal space on a PCB while delivering high functionality. It operates over a broad voltage range from 4.5V to 5.5V, making it compatible with TTL (Transistor-Transistor Logic) levels. This voltage range, combined with a -40°C to +125°C operating temperature, allows the device to function reliably in various environmental conditions.

The device has two serial data inputs (A and B), which can be configured for either single or dual data input modes. In single data input mode, input B can be used as an active LOW clock enable. The clock input is edge-triggered, allowing for precise data capture on the rising edge of the clock signal. Additionally, the 74AHCT164PW incorporates an asynchronous master reset input that clears the register, setting all outputs LOW.

The 74AHCT164PW offers high noise immunity and low power consumption, which are characteristic features of the AHCT family. The low power dissipation and the ability to drive loads with significant capacitance make it an excellent choice for interfacing with output devices. The symmetrical output impedance ensures balanced propagation delays, thereby enhancing the performance of the device in high-speed applications.

With its robust design, the 74AHCT164PW is ideal for use in a variety of digital systems where efficient data handling and space-saving are critical. It is commonly used in microprocessor systems, computers, controllers, and other digital applications requiring high-speed serial-to-parallel data conversion.

In summary, the 74AHCT164PW from NXP Semiconductors is a versatile and reliable component that provides a practical solution for serial-to-parallel data conversion in a wide array of electronic systems.
