W65C21S Data Sheet
This device contains input protection against damage due to
high static voltages or electric fields; however, precautions
should be taken to avoid application of voltages higher than
the maximum rating.
Notes:
1. Exceeding these ratings may cause permanent damage,
functional operation under these conditions is not implied.

Notes:
1. All units are direct current (DC) except for capacitance.
2. Negative sign indicates outward current flow, positive indicates inward flow.
3. Typical values are shown for VDD = 5.0V and TA = 25^○ C
4. All production test loads use test machine capacitance (~30pF) only.
5. Capacitance of all pins is estimated 5.0pF at a 1MHz sample.
