NOTES:
1. All voltages are referenced to ground.
2. Logic 1 voltages are specified at a source current of 1 mA.
3. Logic 0 voltages are specified at a sink current of 4 mA.
4. I

.
5. I
CC
specified with V
CC
at 5.0V and RST =GND.
6. Measured at V
IH
= 2.0V or V
IL
= 0.8V.
7. Measured at V
OH
= 2.4V or V
OL
= 0.4V.
8. Load capacitance = 50 pF.
9. t
