The major problem might be the deviations and temperature drifts of output low voltages of driving gates. Datasheet of 74HC04 e.g. says, that the output low voltage at currents <20µA can be in the range 0...100mV. As 100mV is 1/50 of Vcc=5V, 50 "zeros" can fabricate the same result like one "1".
Another problem is, that real digital circuit suffer from ground bounce and ground noise. This might force you to further decrease the number of lines processed by one OPamp. Kai |
