74HC280D,653 9-Bit Odd/Even Parity Generator/Checker | High-Speed CMOS | SOIC-14 SMD

Description

The 74HC280D,653 is a high-speed, silicon-gate CMOS 9-bit parity generator/checker. This device is specifically designed to detect single-bit errors in data transmission or storage systems. It accepts nine bits of data as input and provides both an EVEN and an ODD output, indicating the parity of the input word.

The parity outputs are generated as follows: the EVEN output is HIGH if an even number of inputs are HIGH, and the ODD output is HIGH if an odd number of inputs are HIGH. This functionality is essential for data integrity verification in computer buses, memory systems, and communication interfaces. Built using the HC (High-Speed CMOS) logic family, it offers low power consumption and high noise immunity. The SOIC-14 surface-mount package ensures a compact, reliable footprint for modern automated PCB assembly.
