概述

Description

The SN74LV165APWR is an 8-bit parallel-in/serial-out shift register designed for high-speed data transfer in digital circuits. It operates on a low voltage (2V to 5.5V), making it suitable for modern low-power applications. The device features a serial output that allows data to be shifted out one bit at a time, making it ideal for applications requiring data serialization.
It can capture parallel data inputs on the rising edge of the clock signal and shift it out on the rising edge of the shift clock. The SN74LV165APWR includes features such as asynchronous reset, enabling easy clearing of the register.
Common uses include interfacing with microcontrollers and digital signal processing applications, as well as expanding input/output capabilities in systems. The device comes in a TSSOP-16 package, which is compact and suitable for space-constrained designs. Overall, it's a versatile component for various digital applications requiring efficient data handling.
