Overview
The SN74HC273NG4 is a member of Texas Instruments' widely used SN7xxx Logic family. It is an octal D-type flip-flop integrated circuit, designed for use in logic and digital logic circuit systems. This device is positive-edge-triggered, meaning that the data at the input is transferred to the output on the positive-going edge of the clock pulse. It features a direct active low clear (CLR) input, allowing for easy reset of the flip-flops. The SN74HC273NG4 is available in a 20-DIP (0.300", 7.62mm) package and is suitable for a variety of digital circuit applications.
