#87473 - Vcc tolerance Responding to: ???'s previous message |
Then the problem must be with Vcc tolerance since AB version requires tighter tolerance and same would be, of course, true for signals to this chip.
Is DS1230AB-120 functional otherwise? Can you check it on a tester or some other circuit? Try changing chip if you have couple of them. |
