*Comments
Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to this device.
These are stress ratings only. Functional operation of
this device at these or any other conditions above those
indicated in the operational sections of this specification
is not implied or intended. Exposure to the absolute
maximum rating conditions for extended periods may
affect device reliability.

Note : 1. All voltages referenced to VSS (GND).
2. Overshoot : VIH ≤ +4.6V for t ≤ tKHKH/2 for I ≤ 20mA
Undershoot : VIL ≥ -0.7V for t ≤ tKHKH/2 for I ≤ 20mA
Power-up : VIH ≤ +3.456V and VCC ≤ 3.135V for t ≤ 200ms
3. MODE pin has an internal pull-up and exhibits an input leakage current of ±10µA.
4. The load used for VOH, VOL testing is shown in Figure 2. AC load current is higher than the shown DC values.
AC I/O curves are available upon request.
5. VCC and VCCQ can be externally wired together to the same power supply.
6. This parameter is sampled.
