Equivalent of STP16C596 in DIP package for through-mount
I use the STP16CP05 for shift-register type environments (as an SOIC chip - not through hole, but easy to hand solder anyway).

For more complex environments requiring PWM I use the I2C controlled TLC59116. I use it as a TSSOP, but I believe it's available as PDIP.

Both are LED drivers and control up to 16 LEDs each.
