Electrical Specifications

9.1

Absolute Maximum Ratings

Notes:

1. Minimum DC voltage on input or I/O pins is -0.5V. During voltage transitions, input or I/O pins may undershoot VSS to -2.0V for periods of

up to 20 ns. See Figure 9.3 on page 73. Maximum DC voltage on input or I/O pins is VCC +0.5V. During voltage transitions, input or I/O

pins may overshoot to VCC +2.0V for periods up to 20 ns. See Figure 9.4 on page 73

2. No more than one output may be shorted to ground at a time. Duration of the short circuit should not be greater than one second.

3. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only;

functional operation of the device at these or any other conditions above those indicated in the operational sections of this data sheet is

not implied. Exposure of the device to absolute maximum rating conditions for extended periods may affect device reliability.

Latchup Characteristics

This product complies with JEDEC standard JESD78C latchup testing requirements.

9.3

Operating Ranges

9.3.1

Temperature Ranges

Industrial (I) Devices

Ambient Temperature (TA)

-40°C to +85°C

9.3.2

Power Supply Voltages

VCC

2.7V to 3.6V

VIO

1.65V to VCC + 200 mV

Operating ranges define those limits between which the functionality of the device is guaranteed.

9.3.3

Power-Up and Power-Down

During power-up or power-down VCC must always be greater than or equal to VIO (VCC ≥ VIO).

The device ignores all inputs until a time delay of tVCS has elapsed after the moment that VCC and VIO both

rise above, and stay above, the minimum VCC and VIO thresholds. During tVCS the device is performing power

on reset operations.

During power-down or voltage drops below VCC Lockout maximum (VLKO), the VCC and VIO voltages must

drop below VCC Reset (VRST) minimum for a period of tPD for the part to initialize correctly when VCC and VIO

again rise to their operating ranges. See Figure 9.2 on page 72. If during a voltage drop the VCC stays above

VLKO maximum the part will stay initialized and will work correctly when VCC is again above VCC minimum. If

the part locks up from improper initialization, a hardware reset can be used to initialize the part correctly.

Normal precautions must be taken for supply decoupling to stabilize the VCC and VIO power supplies. Each

device in a system should have the VCC and VIO power supplies decoupled by a suitable capacitor close to

the package connections (this capacitor is generally on the order of 0.1 µF). At no time should VIO be greater

then 200 mV above VCC (VCC ≥ VIO - 200 mV).
