2. Negative injection disturbs the analog performance of the device. See Note: on page 66.
Injected current five volt tolerant pins(3)
3. Positive injection is not possible on these I/Os. A negative injection is induced by VIN<VSS. IINJ(PIN) must
never be exceeded. Refer to Table 5 for maximum allowed input voltage values.
−5/+0
Injected current on any other pin(4)
4. A positive injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS. IINJ(PIN) must
never be exceeded. Refer to Table 5 for maximum allowed input voltage values.
± 5
ΣIINJ(PIN)
Total injected current (sum of all I/O and control pins)(5)
5. When several inputs are submitted to a current injection, the maximum
ΣIINJ(PIN) is the absolute sum of the
positive and negative injected currents (instantaneous values).
