Answer 2

The 74180 is an 8 bit parity generator/checker.

1. Input
2. Input
3. Even Control
4. Odd Control
5. Even Output
6. Odd Output
7. Ground
8. Input
9. Input
10. Input
11. Input
12. Input
13. Input
14. +5V

If Even and Odd Control are both high, both Even and Odd Output are low.

If Even and Odd Control are both low, both Even and Odd Output are high.

If Even Control is low, and Odd Control is high, then Even Output is high if the number if inputs that are high is even, and Odd Output is the inverse of that. The reverse is true if Even Control is high and Odd Control is low.
