Description
The Intersil ACTS280MS is a Radiation Hardened 9-bit odd/even parity generator checker device. Both odd and even parity outputs are available for generating or checking parity for words up to 9 bits long. Even parity is indicated (EVEN output high) when an even number of data inputs are high. Odd parity is indicated (ODD output high) when an odd number of data inputs are high. Parity checking for larger words can be accomplished by tying EVEN output to any input of an additional ACTS280MS.
