Overview
The SN74HC273DWR is a positive-edge-triggered D-type flip-flop integrated circuit produced by Texas Instruments. It is part of the 74HC series and is known for its wide operating voltage range and low power consumption. This device contains eight D-type flip-flops with single-rail outputs and a direct active low clear (CLR) input. The flip-flops are triggered on the positive-going edge of the clock (CLK) pulse, making it suitable for various digital logic applications.
