Overview
The CD74AC273M is an octal D-type flip-flop integrated circuit manufactured by Texas Instruments. This device utilizes advanced CMOS logic technology and is part of the high-speed CMOS (AC) family. It features eight D-type flip-flops, each controlled by a common clock (CP) and a common reset (MR). The flip-flops transfer information from the D input to the Q output on the positive-going edge of the clock pulse, and resetting is accomplished by a low voltage level independent of the clock.
