Texas Instruments CD74ACT280 Manuals

Harris Semiconductor SCHS250A is a 9-bit odd/even parity generator/checker that utilizes Advanced CMOS Logic technology. It features balanced propagation delays, high speed, and reduced power consumption. It can be used to check or generate odd/even parity for words up to nine bits long. Even parity is indicated when an even number of data inputs is HIGH, and odd parity is indicated when an odd number of data inputs is HIGH.

CD54AC280, CD54ACT280 are 9-bit odd/even parity generator/checkers that utilize 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 par- ity is indicated (∑E output is HIGH) when an even number of data inputs is HIGH. Odd parity is indicated (∑O output is HIGH) when an odd number of data inputs is HIGH. Parity checking for words larger than nine bits can be accom- plished by tying the ∑E output to any input of an additional 'AC280, 'ACT280 parity checker.

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.
