*Stresses above those listed under "Absolute Maximum Ratings" may
cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions above
those indicated in the operational sections of the specifications is not
implied. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
NOTES: 1. This limit refers to that of the package and will not be realized
2. Due to the SCR structure inherent in the CMOS process,
during normal operation.
connecting any terminal to voltages greater than V
than GND may cause destructive latch-up. For this reason, it
is recommended that inputs from external sources not oper-
ating on the same power supply not be applied to the device
before its supply is established, and, in multiple supply
systems, the supply to the TC7211AM be turned on first.
