Look at my Pertec-interface controller board. All through-hole, but for
the MCU board (easier to buy than to build). You can see the 74ABT573
drivers for the drive cable. I run my own on 3m cables with no problems.

Thru the hole and 5 volt and cheap and easy to find ( at one time ) and

Before you say use XXX , I don't have the skills or the tools to layout
and debug high tech boards or parts. I am very unlucky with FPGA stuff. I keep finding I still need 74XX just for having
10 TTL loads,
and 74LSXX just does not have the power.
Ever try BiCMOS chips? IIRC, the 74ABTxxx will drive loads of up to 60
ma, far in excess of old 74xx parts.
