NXP 74HCT165PW 8-bit Parallel-Load Shift Registers
The NXP 74HCT165PW is a high-speed Si-gate CMOS device that belongs to a high-performance family of 8-bit shift registers. This integrated circuit is designed to interface with 5 V systems, offering a perfect solution for digital data storage and transfer. It is particularly well-suited for applications that require the capture and serial-to-parallel conversion of data, such as in data acquisition systems, digital processing, and various control systems.
The 74HCT165PW features an 8-bit parallel load shift register with synchronous serial data output. The device can operate in two modes: parallel (load) mode and serial (shift) mode. In the load mode, data is entered into the register on the rising edge of the clock (CP) pulse when the shift/load (SH/LD) input is low. In the shift mode, data is shifted on the rising edge of the clock pulse when SH/LD is high.
Additional features of the NXP 74HCT165PW include an asynchronous master reset (MR) input that clears the register, setting all outputs low when applied with a high logic level. The clock input is a Schmitt-trigger, which allows for jitter-free clock input signals with slow rising or falling edges. This enhances the device's performance in environments with noisy signals.
The 74HCT165PW comes in a TSSOP16 package, which is a thin shrink small outline package with 16 leads. It is compact and suitable for surface-mount technology (SMT), making it ideal for use in space-constrained applications. The device's pin configuration is optimized for easy PCB layout and interfacing with microcontrollers and other logic devices.
With its wide operating temperature range and the ability to directly drive TTL levels, the 74HCT165PW is a versatile component for a myriad of digital applications. Its low power consumption and high noise immunity characteristics conform to the JEDEC standard no. 7A requirements, ensuring reliable performance and compatibility with other logic families.
Whether you're designing a complex digital system or simply need a reliable way to capture and convert parallel data to serial format, the NXP 74HCT165PW offers a robust and efficient solution.
