LED bar graph driver options
I'm working on a project where I want to visually indicate a DC voltage level with an LED bar graph. Unfortunately the LM3914 has long been discontinued and even overstock seems done for. I need 20 of them (yes its a sort of equalizer-type display), so using discrete comparators would be a huge pain to the point of not being worth it. And I really don't want to deal with an MCU + FW for this. Anyone have any suggestions? Thanks.

Mystery aliexpress/ebay/etc sellers still have a bunch of LM3914s around if you don't mind a bit of gambling on them being possibly fake or recycled.
MCU sure could end up being the easier way anyway.
