Overview
The SN74HC273NS is a part of the SNx4HC273 family of integrated circuits produced by Texas Instruments. This device is an octal D-type flip-flop with a direct active low clear (CLR) input. It is designed to operate within a wide voltage range and is suitable for various digital logic applications. The SN74HC273NS 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.
