i was re-checking the specs on the A618SEP replacement for my SN75518N .... advertised as drop in replacement
and i noticed that the minimum clock for A6818 is 10 MHz @ 5v and the SN75518 has a 1-5 MHz range @ 5v which is quite a ways out of spec from the replacement's specs
do you suppose the A6818 will work in the 1-5 MHz range ?
what is the experience with these sorts of operational minimums ? i guess they would not state a minimum if there was no real minimum ?
if it turns out that the a6818 does not function due to spec differences what would (is there something) one could do to get this replacement to work ?
i have not tried yet but imagined this may be a problem and did not wnat to start etching my adapter if there is some solution/control chip i will need to add to my adapter
thanks for any advice, rob
