I/O PORT PIN CHARACTERISTICS (Cont’d)

12.8.2 Output Driving Current

Subject to general operating conditions for VDD, fCPU, and TA unless otherwise specified.

Figure 82. Typical VOL at VDD=5V (standard)

Figure 83. Typical VOL at VDD=5V (high-sink)

Figure 84. Typical VOH at VDD=5V

Notes:

1. The IIO current sunk must always respect the absolute maximum rating specified in Section 12.2.2 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 12.2.2 and the sum of

IIO (I/O ports and control pins) must not exceed IVDD. True open drain I/O pins do not have VOH.
