The 74LS273N is a popular integrated circuit from Signetics belonging to the 74xx series of TTL digital logic chips. It functions as an octal D-type flip-flop with a clear input, meaning it contains eight individual flip-flops within a single package.
Key features include eight data inputs (D0-D7), a clock input (CP) that triggers on the rising edge, and a master reset input (MR) that is active-low. The outputs are Q0-Q7 and their complements Q̅0-Q̅7. The typical operating voltage for this component is 5V.
This IC is commonly available in a DIP-20 package, making it suitable for breadboarding and through-hole mounting. Its design makes it useful for applications such as data storage, address decoding, and general-purpose sequential logic where multiple flip-flops are required.
Numerous arcade games and pinball machines utilize the 74LS273, including titles like Pac-Man, Galaga, and Donkey Kong 3, highlighting its historical significance in retro gaming hardware.
