Vdd on the 5530 should be about 12V - the schematic snippet implies that Vdd is 5V - the data sheet explicitly states that normal operation is not guaranteed with Vdd below 10.8V.
It may have worked at 5V, but that's just luck... over time, who knows what else has drifted.. Nick -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
