generated)
Data setup time
Data hold time:
Input high voltage level
Input low voltage level
Low level output voltage
Output fall time from V
from 10 to 400 pF
Pulse width of spikes which must be suppressed by the input filter t
Input current each I/O pin (input voltage is between 0.1 × OV
and 0.9 × OV
Capacitance for each I/O pin
Notes:
1. Output voltage (open drain or open collector) condition = 3 mA sink current.
