Thanks for the quick reply, Grahame. I will be driving mine from a PIC. I might do a layout which has the PIC on the board, but only populate one of the boards with the PIC. using these devices sure reduces the number of IOs needed.

Nigel, I have used the 5522 without issue. The 5523 appears to be a "better" device with higher clock frequency and 5V logic. I use the blanking input on the 5522 and a PWM output from the uC for dimming. I have used th 5522 with 5V logic directly and 3V3 logic (from a raspberrypi) via a level shifter. Finally, I've chained 3 together to give 96 HV outputs. I normally use the SPI output rather than bit bang. So, not quite your question answered but I would have no immediate concerns.

I just wondered if anyone else had used these devices and if so, were there any issues? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
