1. General description

The 74HC280; 74HCT280 is a 9-bit parity generator or checker. Both even and odd parity outputs

are available. The even parity output (PE) is HIGH when an even number of data inputs (I0 to I8)

is HIGH. The odd parity output (PO) is HIGH when an odd number of data inputs are HIGH.

Expansion to larger word sizes is accomplished by tying the even outputs (PE) of up to nine

parallel devices to the final stage data inputs. Inputs include clamp diodes. It enables the use of

current limiting resistors to interface inputs to voltages in excess of VCC.

2. Features and benefits
