Pin Assignment

The TC74HC280A is a high speed CMOS 9-BIT PARITY

It achieves the high speed operation similar to equivalent

The TC74HC280A is composed of nine data inputs A thru I and

The odd parity output is high when an odd number of data

The word-length capability is easily expanded by cascading.

All inputs are equipped with protection circuits against static
