Hi all- I had a question on driving nixies using something other than 74141s. Would any driver that can sink higher currents work ok? Am I right in assuming I can use a driver that sinks with nixies because the cathodes are connected to ground when not floating?
For example, would this one work to use as a shift register? I realize I won't need one for my current project that already has 74141s wired into the circuit, but was thinking ahead to building a clock from scratch. "Add a bunch of high-power outputs to a microcontroller system with chainable shift registers. These chips take a serial input (SPI) of 1 byte (8 bits) and then output those digital bits onto 8 pins. You can chain them together so putting three in a row with the serial output of one plugged into the serial input of another to make 3 x 8 = 24 digital outputs. You can chain pretty much as many as you want. This makes it easy to control a lot of outputs like LEDs from only 3 digital microcontroller pins. This item contains *one TPIC6B595 chip*! These chips similarly to the more well known 7HC595s but they are high power drains, able to sink 150mA per pin." https://www.adafruit.com/products/457 As always thanks to the list for your advice and info. -Dylan -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
