I/O PORT PIN CHARACTERISTICS (Cont’d)
9.8.2 Output Driving Current
Subject to general operating conditions for VDD, fOSC, and TA unless otherwise specified.
Figure 83. Typical VOL at VDD=5V (standard)
Figure 84. Typical VOL at VDD=5V (high-sink)
Figure 85. Typical VDD-VOH at VDD=5V
Notes:
1. The IIO current sunk must always respect the absolute maximum rating specified in Section 9.2.2 and the sum of IIO
(I/O ports and control pins) must not exceed IVSS.
2. The IIO current sourced must always respect the absolute maximum rating specified in Section 9.2.2 and the sum of
IIO (I/O ports and control pins) must not exceed IVDD. True open drain I/O pins does not have VOH.
