The document describes the features and characteristics of Harris Semiconductor SCHS250, including buffered inputs, propagation delay, ESD protection, CMOS process and circuit design, power consumption, noise immunity, etc.
The CD74AC280 and CD74ACT280 are 9-bit odd/even parity generator/checkers that utilize Harris Advanced CMOS Logic technology. Both even and odd parity outputs are available for checking or generating parity for words up to nine bits long. Even parity is indicated when an even number of data inputs is HIGH, while odd parity is indicated when an odd number of data inputs is HIGH.
