Is there such a thing as a jellybean 74- or 4000-series part that takes a binary or BCD input and drives a bar graph LED from it?
I need to drive an 8-LED bar graph from a 4-bit data source with the minimum of components, and right now the simplest option appears to be a micro (well, or a PAL, but it's easier for me to develop a micro).
The drive lines are output-only and can't be switched very quickly, so that rules out putting an I2C or SPI I/O expander on them.
