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*V
CC
. 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: C
L
= 125pF, except open drain outputs. Test conditions for open drain outputs: C
L
= 125pF,
constant current source = 2.6mA.
5. Input port pins have active pull-up transistors that will source a typical 2
