[Actually, I'll admit to having fed the
output of an HCT04 (or
similar)
into a serial port once. My excuse it that it
waas a one-off test
board,
and I had the schematics of the serial card it
was driving (which
showed
a 1489 reciever).
I once used a dual opamp in an 8-pin DIL to do that. One half was the
receiver, one the driver. I knew that what I was driving wouldn't
overload the opamp's output, and it kept the chip count down (it was a
small microcomputer based on a Z8, on a board about 3" square).
