| Part Number | Description |
|---|---|
| HEF4532B | 8-input priority encoder |
| HEF4534B | Real time 5-decade counter |
| HEF4538B | Dual precision monostable multivibrator |
| HEF4539B | Dual 4-input multiplexer |
| HEF4502B | Strobed hex inverter/buffer |
The HEF4531B is a parity checker/generator with 13 parity inputs (I0 to I12) and a parity output (O). When the number of parity inputs that are HIGH is even, the output is LOW. When the number of parity inputs that are HIGH is odd, the output is HIGH.
