Overview
The CD74ACT273MPWREP is an octal D-type flip-flop with reset, manufactured by Texas Instruments. This device utilizes advanced CMOS logic technology, offering high performance and low power consumption. The flip-flops are controlled by a common clock (CP) and a common reset (MR), allowing for synchronized operation. Information at the D input is transferred to the Q output on the positive-going edge of the clock pulse, making it suitable for a variety of digital logic applications.
