National Semiconductor MM5486N LED Display Driver.
TTL compatible.
For individual LEDs, 7 segment displays, or even for relays.
40 Pin Dip. Serial I/O.
Very useful and were very popular back in the mid 80's.
33 outputs that will sink 15 ma. Versatile and easy to use.
Optimized for common anode. With a brightness control.
[it is essentially a 33 bit shift register
with current-adjustable outputs via one pin to a resistor.
It cascades too!]
