SN75468, SN75469 SLRS023E – DECEMBER 1976 – REVISED JANUARY 2015 www.ti.com 11 Power Supply Recommendations This part does not need a power supply; however, the COM pin is typically tied to the system power supply. When this is the case, it is very important to make sure that the output voltage does not heavily exceed the COM pin voltage. This will heavily forward bias the fly-back diodes and cause a large current to flow into COM, potentially damaging the on-chip metal or over-heating the part.
