Hello all,

I'm trying to drive an array of <= 16 LEDs from a PIC, hopefully using a
single surface mount part. Ideally, the part would directly drive the LEDs,
perhaps with an external resistor to set the constant current, and would be
serially controlled. The MM5450, which was a Micrel part but seems to have
been made by all sorts of people, was ideal for this, but it's a huge 40 pin
DIP. I've searched high and low and have been unable to find a single chip
solution for this; in the past I've used a shift register connected to a
transistor array connected to current limiting resistors connected to the
hip bone...
I don't need to multiplex anything, I just want to be able to individually
control a series of tiny SM LEDs with a single part (this all goes on a very
small board.)
I'd appreciate any ideas at all, especially if there is something I'm
missing.
Thanks,

Evan.
