Many of the signals, as indicated in the table above, are high-speed
CMOS logic inputs or outputs powered from a 2.75V±5% internal
voltage regulator, and are defined as Digital 2.75V. Whenever a signal
is defined as Digital 2.75V, the following electrical characteristics
apply.

• All 2.75V digital inputs will continuously withstand and suffer no
damage in the power-on or power-off condition when subjected to
any voltage from -0.5V to 3.47V (3.3V+5%).
• All 2.75V digital outputs will continuously withstand a short circuit
to any other voltage within the range 0V to 3V.
• All analogue outputs will continuously withstand a short circuit to
any voltage within the range 0V to 3V.
• The SIM output signals and the SIMVCC supply will continuously
withstand a short circuit to any voltage within the range 0V to 5.8V.
