74HC273 Octal D-Type Flip-Flop with Reset IC - DIP-20 Package is a high-speed CMOS logic IC featuring eight edge-triggered D-type flip-flops with a common clock and asynchronous master reset. Data present at the D inputs is transferred to the outputs on the low-to-high transition of the clock signal, while the master reset clears all outputs regardless of the clock. The 74HC273 is widely used in digital storage, data buffering, microprocessor interfacing, register circuits, and embedded system applications.
