audioguru Posted August 19, 2006 Report Share Posted August 19, 2006 Those old parts were made and sold about 20 or 30 years ago. I don't know anywhere that would still have a few. I don't have a list of modern substitutes. Quote Link to comment Share on other sites More sharing options...

ante Posted August 20, 2006 Report Share Posted August 20, 2006 Hi Peron,You can almost always replace these two ICs with one ICL7107. ;) Quote Link to comment Share on other sites More sharing options...
Muhammad Abu Bakar Posted August 20, 2006 Report Share Posted August 20, 2006 ICL7107?A lot of wiring mesh to do. Just compare 10 Vs 23 pins you have to feed. Quote Link to comment Share on other sites More sharing options...
ante Posted August 20, 2006 Report Share Posted August 20, 2006 I don’t see your point here!The CA3161 has 16 pins so has the CA3162.The ICL7107 has 40 pins.?? Quote Link to comment Share on other sites More sharing options...
audioguru Posted August 21, 2006 Report Share Posted August 21, 2006 The CA3161 and CA3162 multiplex the display so the wiring to the display is not much.The ICL7107 has direct drive to each segment of the display so it has lots of wiring (wiring mess?).

ante Posted August 21, 2006 Report Share Posted August 21, 2006 Hi AG,Ok, I see what you mean. On the other hand the ICL7107 is available in any convenient store but the CA3161 & CA3162 is not! ;) Quote Link to comment Share on other sites More sharing options...
Muhammad Abu Bakar Posted August 21, 2006 Report Share Posted August 21, 2006 Hello AG,You got my point.Hello Ante,I saw some other IC'pairs doing the same functionality. But I don't remeber there exact ID's Quote Link to comment Share on other sites More sharing options...
