Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I6 | input | Data input I6 is one of the nine data inputs (I0 to I8) counted for parity; inputs include clamp diodes so current-limiting resistors can interface them to voltages above VCC, with input clamping current limited to ±20 mA when VI < -0.5 V or VI > VCC+0.5 V. |
| 2 | I7 | input | Data input I7 is one of the nine data inputs (I0 to I8) counted for parity; inputs include clamp diodes, with input clamping current limited to ±20 mA when VI < -0.5 V or VI > VCC+0.5 V. |
| 3 | n.c. | unconnected | Not connected; the datasheet lists this pin as n.c. with no internal function. |
| 4 | I8 | input | Data input I8 is one of the nine data inputs (I0 to I8) counted for parity; inputs include clamp diodes, with input clamping current limited to ±20 mA when VI < -0.5 V or VI > VCC+0.5 V. |
| 5 | PE | output | Even parity output that is HIGH when an even number of data inputs (I0 to I8) is HIGH; it can be tied to the data inputs of a final stage to expand word length. |
| 6 | PO | output | Odd parity output that is HIGH when an odd number of data inputs (I0 to I8) is HIGH. |
| 7 | GND | power_in | Ground (0 V) reference for all voltages in the datasheet. |
| 8 | I0 | input | Data input I0 is one of the nine data inputs (I0 to I8) counted for parity; inputs include clamp diodes, with input clamping current limited to ±20 mA when VI < -0.5 V or VI > VCC+0.5 V. |
| 9 | I1 | input | Data input I1 is one of the nine data inputs (I0 to I8) counted for parity; inputs include clamp diodes, with input clamping current limited to ±20 mA when VI < -0.5 V or VI > VCC+0.5 V. |
| 10 | I2 | input | Data input I2 is one of the nine data inputs (I0 to I8) counted for parity; inputs include clamp diodes, with input clamping current limited to ±20 mA when VI < -0.5 V or VI > VCC+0.5 V. |
| 11 | I3 | input | Data input I3 is one of the nine data inputs (I0 to I8) counted for parity; inputs include clamp diodes, with input clamping current limited to ±20 mA when VI < -0.5 V or VI > VCC+0.5 V. |
| 12 | I4 | input | Data input I4 is one of the nine data inputs (I0 to I8) counted for parity; inputs include clamp diodes, with input clamping current limited to ±20 mA when VI < -0.5 V or VI > VCC+0.5 V. |
| 13 | I5 | input | Data input I5 is one of the nine data inputs (I0 to I8) counted for parity; inputs include clamp diodes, with input clamping current limited to ±20 mA when VI < -0.5 V or VI > VCC+0.5 V. |
| 14 | VCC | power_in | Supply voltage; the recommended operating range is 2.0 V to 6.0 V (typical 5.0 V), referenced to GND. |
