Product Overview: 74HCT164N by NXP

The 74HCT164N 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 is specifically engineered to deliver exceptional performance in a wide range of digital applications. The 74HCT164N is a member of the 74HCT family, which is known for its compatibility with TTL (Transistor-Transistor Logic) levels while operating at the lower power consumption characteristic of CMOS technology.

This integrated circuit 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 and synchronous reset of all eight output bits to the low state when applied with a high logic level. The serial data is entered at the A and B inputs and is shifted through the register on the rising edge of the clock input signal.

With its robust design, the 74HCT164N is capable of driving up to 15 LSTTL loads and has a high noise immunity characteristic of CMOS. The IC operates across a wide voltage range from 4.5V to 5.5V, making it suitable for interfacing with both 5V TTL logic and microprocessor systems. It is also characterized for operation from -40°C to +125°C, ensuring reliable performance across extreme temperature ranges.

The 74HCT164N is available in a 14-pin DIP (Dual In-line Package), which is a common package type used in through-hole PCB designs. This package is well-suited for prototyping, educational purposes, and in environments where manual assembly or replacements are necessary.

Typical applications for the 74HCT164N include:

• Serial-to-parallel data conversion
• Remote control holding registers
• Sequential logic operations
• Extended I/O ports for microprocessors and microcontrollers

Overall, the 74HCT164N from NXP is a reliable and versatile shift register that offers the functionality needed for a variety of digital circuits, making it an essential component for electronics designers and hobbyists alike.
