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 0.4V and 3.0V with a transition time of

5ns maximum. For X1/CLK, this swing is between 0.4V and 0.8*VCC. All time measurements are referenced at input voltages of 0.8V and

2.0V and output voltages of 0.8V and 2.0V, as appropriate.

3. Typical values are at +25°C, typical supply voltages, and typical processing parameters.

4. Test conditions for outputs: CL = 125pF, except open drain outputs. Test conditions for open drain outputs: CL = 125pF,

constant current source = 2.6mA.

5. Input port pins have active pull-up transistors that will source a typical 2µA from VCC when the input pins are at VSS.

Input port pins at VCC source 0.0µA.

6. All outputs are disconnected. Inputs are switching between CMOS levels of VCC –0.2V and VSS+0.2V.
