This chapter specifies on the one hand the electrical characteristics of device inputs and
power needed to guarantee proper operation of the IEC-Q. On the other hand it specifies
the electrical characteristics of the IEC-Q outputs, power consumption and analog
functions.
Note 76:
Sections 8.1 and 8.2 describe the maximum ratings allowed and the power supply
needed.
Section 8.3 specifies the maximal overload which can be imposed directly on the IEC-Q
line interface, without causing device damage.
Sections 8.4 and 8.5 specify the power consumption and the analog functions (e.g. ADC
and DAC performance).
Section 8.6 describes the DC characteristics of the IEC-Q.
The dynamic characteristics of the microprocessor interface, the IOM
power controller interface, the undervoltage detection block and device clock are given
in section 8.7.
