It sounds like you are describing the TIL311. They are very nice. I
have a number of them (with me here) and have worked with them since
my first Elf in the late 1970s. Unfortunately, for what I am trying to
do, they aren't my first choice - I have an existing mechanical spacing
that I'm trying to stay compatible with, and it's too wide for a reasonable
bank of TIL311s.
Has anyone here worked with or ever plotted
silently to create a moderish
7-segment decoder/driver from a GAL16V8? I'm working on a project made
from classic parts...
I have build a small clock, and did not want to do much wiring,
so I used 73LS390 and those fancy HP "7-segment" displays
that display the numbers in a series of dots. Old HP counters have them. The dimensioning is such that they can be
"stacked", put neatly next to
each other. As these displays have the 7-segment decoder and the BCD latch
inside, it made the wiring/soldering quite easy, and you get a "cool display"
:-)
They do stack nicely, and they do make a cool display. Unfortunately, I
need something that's about 0.2" wider than a TIL311, and that happens to
be some HP 7-segment displays, which is why I asked about the 7447 rather
than going off and doing my own thing with TIL311s.
