SN74LVC541A-Q1: unused pins

Hailiang Zhang

Part Number: SN74LVC541A-Q1

Hi Team,

Please help confirm that considering that SN74LVC541A-Q1 uses three-state CMOS output, should the unused output pins be left floating?

Hi Hailiang,

Yes, unused CMOS outputs should be left floating. For more tips on terminating CMOS I/O pins, please see this FAQ: [FAQ] How do I terminate any unused channels of a logic device?

Best,

Ian
