Product Overview: 74AHCT164 from NXP Semiconductors

The 74AHCT164 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 integrates advanced circuitry to offer a seamless and efficient solution for a wide variety of digital applications. This component is particularly well-suited for systems that require the conversion of serial data to parallel format, making it an ideal choice for interfacing with microprocessors and microcontrollers in complex digital systems.

The device features two serial data inputs (A and B) that can be configured for single or dual data streams, allowing for flexibility in handling serial data. The eight parallel output pins (Q0 to Q7) present the data in a parallel format, which can then be utilized by other components within the system. The shift register operates with a positive-edge clock input (CP) and a master reset input (MR) that clears the register, setting all outputs low when a high signal is applied.

One of the key advantages of the 74AHCT164 is its compatibility with TTL levels. This makes it an excellent choice for interfacing with older TTL logic devices while benefiting from the low power consumption and high noise immunity of CMOS technology. The operating voltage range of 4.5V to 5.5V allows for a stable operation in 5V systems, which is common in many digital electronic applications.

With its high noise immunity and the ability to drive up to 15 LSTTL loads, the 74AHCT164 is highly reliable and can be used in environments with a significant amount of electrical noise. The device also features an ESD protection for enhanced durability against electrostatic discharge events.

Overall, the NXP 74AHCT164 shift register is a robust and versatile component that provides designers with a reliable and efficient means to handle serial-to-parallel data conversion. Its compatibility with TTL and LSTTL logic levels, along with its low power consumption and high noise immunity, make it an excellent choice for a broad range of digital applications.
