概要

Description

The SN74LV273APWR is a low-voltage, high-speed octal D-type flip-flop designed by Texas Instruments. It operates with a supply voltage range of 2.7V to 3.6V, making it suitable for battery-operated devices and low-power applications. The device features eight D-type flip-flops that capture data on the rising edge of the clock input (CLK). It includes asynchronous set (SET) and reset (RESET) functionality, allowing for immediate control of output states.
The flip-flops are implemented in a 20-pin TSSOP package (PWR), making it compact for integration into various designs. Its high-speed capabilities enable data processing at rates up to 150 MHz, essential for modern digital circuits. The SN74LV273APWR is commonly used in applications such as data storage, state machines, and digital signal processing where reliable data storage and quick response times are critical.
