lingxingic · Parity Generators And Checkers · DIP-14

SN74LS280N from lingxingic, in a DIP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

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.
