LM3914: N/C pin of PLCC Package

masahiko shimizu

Part Number: LM3914

Hi,

My customer is using LM3914V(PLCC Package).
This device has N/C pins which are 7 and 9 pin.
Are those pins connected anything internally?

My customer wants to know whether 7 and 9 pins must not connected to other pin, Vcc or GND, or not.

Best regards,
Shimizu

Hello Shimizu,

For LM3914 PLCC package, pins 7 and 9 should be left floating on the board i.e they should not connect to any other pin, signal, GND or VCC on the board and should be completely left floating.

Kind Regards,
Liaqat
