Working Principles

The M74HC280YRM13TR operates based on the principles of digital logic. It takes a 9-bit binary input and generates or checks its parity based on the control input (G). When G is low, the IC functions as a parity generator, producing the parity bit at the output pin (P). Conversely, when G is high, it operates as a parity checker, comparing the input parity with the calculated parity and indicating any errors through the carry-out pin (C4).
