I'm using two SN75176B, one for RX lines, and one for TX lines. Chip has 8 pins, that is 6 w/o power.
I'd like to replace two chips with one. Instead of R, RE, D, DE, A, B (6 pins) I want R, RA, RB, D, DA, DB (6 pins)
But I can't find it...

I had to look to see if they still made that old dinosaur. I was using it in the early
80's.
Thanks, that got me started and I've found these two: SP490E and SN75179B
