Although each I/O port can sink more than the test conditions (0.5 mA at VCC = 1.8V) under steady state conditions (non-transient), the following must be observed: 1] The sum of all IOL, for ports B0 - B5, should not exceed 50 mA. If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test condition. 4. Although each I/O port can source more than the test conditions (0.5 mA at Vcc = 1.8V) under steady state conditions (non-transient), the following must be observed: 1] The sum of all IOH, for ports B0 - B5 should not exceed 50 mA. If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current greater than the listed test condition. 4 ATtiny25/45/85 7669D–AVR–04/10 ATtiny25/45/85 2.
