Luka - What segment currents are you using for the 7971 ? If you turn all segments on at the rated datasheet current, there are several characters, such as 8 and Q, that will cause the total current to significantly exceed the max rating of 22mA. I analyzed current-draw for most characters, and even the average (~26mA) exceeds spec.
I scaled-back the current in my design so I never exceed the max 22mA. 7971's are really expensive & rare, so I'm not taking any chances. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
