 Bigger Bigger  Smaller Smaller  Reset Reset

I'm looking to drive a display with 43 separate segments, each drawing max 20mA. Perhaps by using latches, or daisy-chained 7-segment ICs, but I'm worried it will draw too much current for that. Any simple solutions?

All on at once?

Have a look at the MAX6954, that will be able to drive your display.

Not without seeing the device. Is this a 5-digit 7-segment display with a couple more lights? 16 pins?
If so, or if similar, multplexing will be required.
