| Considerations for using CMOS Integrated Circuits(ICs)s |
* Answer
| The CMOS Integrated Circuits(ICs) should not be mounted or detached with the power turned on.All instruments and instruments of CMOS Integrated Circuits(ICs)s should be well grounded during testing.Make the input current not exceed 5mA to avoid the burning of the protection diode inside the CMOS Integrated Circuits(ICs).If the signal source and the CMOS Integrated Circuits(ICs) use two sets of power supplies, when starting up, the CMOS Integrated Circuits(ICs) power supply should be connected first, and then the signal source power supply should be turned on.Installation of CMOS Integrated Circuits(ICs)s.In addition, CMOS Integrated Circuits(ICs)s with different package types and pin arrangements are generally not directly replaceable.If you need to use it, you should make some corresponding transformations so that the two terminals with the same function have a one-to-one correspondence.When shutting down, the signal source power should be turned off first, and then the CMOS Integrated Circuits(ICs) power supply should be turned off.Protection measures for CMOS Integrated Circuits(ICs)s.Interchange of MOS Integrated Circuits(ICs)s.Some CMOS Integrated Circuits(ICs)s can be directly used in use.For example, the domestic CC4000 can be directly replaced with the foreign products CD4000 and MC14000 series.For CMOS Integrated Circuits(ICs)s where the pin arrangement and package form are identical, but the electrical parameters are different, pay attention to it when switching. |
