Subject: Re: substitute for TI TIL306/307 Display?
Date: Fri, 03 Jan 2003 17:00:23
The 306/307s also have built in BCD decoders. I've been trying to find
a data sheet on the 311 so that I can see what the difference is between it
and the 306/307.

Hi,
TIL306/7 is a decadecounter, latch, dekoder+driver and led-bar display, and has
a puls-input to the counter.
TIl308/9 is a latch, dekoder+driver and led-bar display, and has BCD-inputs for
data to be displayed.
306 and 308 are identical in its display-dimensions and aparance, the function
differs however. To use a TIL 308 as a replacement for a 306 you will need to
add externalley somewhere a 7490 decade-counter between the original circuit
and the TIL308.
I have a few TIL308 available, if this rework is feasable to you.
TIl310/1 is a latch, dekoder+driver and led-pixel display, and has BCD-inputs
for data to be displayed. Thisone also needs an external 7490 counter in your
usage, on top of that, the display has a different appearance.
Someone else could have those for you.
So, choose the alternative that best suits you, I would continue to search for
the original TIL306, or change the whole display to something else althogether.
