Hi. I wonder if it is possible to program a PAL or GAL to "build" a 74C926 (4-digit counter with multiplexed 7-segment output drivers) and if it' s possible if anyone have the code to program this (and the PAL/GAL marking). This is because the74C926 is very expensive and I have some PAL ready to use.
Thanks.
PS: Sorry me if I said a stupid thing but I never used programming logic devices.

Hi.
Do you know where to find a good guide (with examples) to know and to program PLD, GAL, PAL ?
I never used them so I don't know what are macrocells... I only know that this PLD can be used to create a logic net burning "microswitches" on their inside.
The IC (74C926) I'm looking for has 7 output lines (a to f) to pilote 7-segment displays and 4 output lines multiplexed (so these scans 4 displays connected in parallel scanning their cathodes).
The pins are:
7 output (a-f) for the 7 segments of the displays
4 multiplexed output for the scanning
1 latch enable
1 display select
1 clock
1 reset
1 carry out
I attach the datasheet, if you want to look at it.
Thanx
