The difference is either in the overall design of the output driver, and they are specifically designed to handle a max voltage, or they are bin-split during final test depending upon measurements. Without knowing the device construction (bipolar vs NMOS) it's hard to know if you can push the envelope, so play it safe and stay within spec limits.
If your anode voltage is below 220 volts, the HV5522 should suffice. I used the HV5530 with an anode supply of +200V, just for extra margin on my IN-18 clock. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
