NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other condition above those indicated in the operation section of this specification is not
implied.
2. For operating at elevated temperatures, the device must be derated based on +150
°C maximum junction temperature.
3. This product includes circuitry specifically designed for the protection of its internal devices from damaging effects of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying any voltages larger than the rated maxima.
4. Parameters are valid over specified temperature and voltage range.

NOTES:
1. Parameters are valid over specified temperature and voltage range.
2. All voltage measurements are referenced to ground (GND). For testing, all inputs swing between 0.4 V and 3.0 V with a transition time of
5 ns maximum. For X1/CLK, this swing is between 0.4 V and 0.8VCC. All time measurements are referenced at input voltages of 0.8 V and
2.0 V and output voltages of 0.8 V and 2.0 V, as appropriate.
3. Typical values are at +25
°C, typical supply voltages, and typical processing parameters.
4. Test conditions for outputs: CL = 125 pF, except open drain outputs. Test conditions for open drain outputs: CL = 125 pF,
constant current source = 2.6 mA.
5. Input port pins have active pull-up transistors that will source a typical 2
A from VCC when the input pins are at VSS.
Input port pins at VCC source 0.0 A.
6. All outputs are disconnected. Inputs are switching between CMOS levels of VCC – 0.2 V and VSS + 0.2 V.
