I/O PORT PIN CHARACTERISTICS (Cont’d)
12.8.2 Output Driving Current
Subject to general operating condition for VDD,fCPU, and TA unless otherwise specified.
Figure 67. Typical VOL at VDD=5V (standard)
Figure 68. Typical VOL at VDD=5V (high-sink)
Figure 69. Typical VDD-VOH at VDD=5V
Notes:
1. The IIO current sunk must always respect the absolute maximum rating specified in Section 12.2 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 12.2 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.
