SN74LS280
9Bit Odd/Even Parity
Generators/Checkers
The SN74LS280 is a Universal 9-Bit Parity Generator/Checker. It
features odd/even outputs to facilitate either odd or even parity. By
cascading, the word length is easily expanded.
The LS280 is designed without the expander input implementation,
but the corresponding function is provided by an input at Pin 4 and the
absence of any connection at Pin 3. This design permits the LS280 to
be substituted for the LS180 which results in improved performance.
The LS280 has buffered inputs to lower the drive requirements to one
LS unit load.
Generates Either Odd or Even Parity for Nine Data Lines
Typical Data-to-Output Delay of only 33 ns
Cascadable for n-Bits
Can Be Used To Upgrade Systems Using MSI Parity Circuits
Typical Power Dissipation = 80 mW
