Right... However TI and Toshiba (and I think ST?) list them as current
production without caveats.

The problem is finding a replacement with similar characteristics. I
think that the target applications for these devices are being filled by
ASSP microcontrollers with high-current drivers built in.

It's simple enough to build something out of discrete components, but
it's easier to use an off-the-shelf part like the ULN28xx.
