Note:

Typical values at 25^oC.
“Min” means the lowest value where the pin is guaranteed to be read as high.
“Max” means the highest value where the pin is guaranteed to be read as low.
Not tested in production.
Although each I/O port can sink more than the test conditions (10 mA at V_CC = 5V, 5 mA at VCC = 3V) under steady-state conditions (non-transient), the sum of all I_OL (for all ports) should not exceed 60 mA. If I_OL exceeds the test conditions, V_OL may exceed the related specification. Pins are not guaranteed to sink current higher than the listed test condition.
Although each I/O port can source more than the test conditions (10 mA at V_CC = 5V, 5 mA at V_CC = 3V) under steady-state conditions (non-transient), the sum of all I_OH (for all ports) should not exceed 60 mA. If I_OH exceeds the test condition, V_OH may exceed the related specification. Pins are not guaranteed to source current higher than the listed test condition.
The RESET pin must tolerate high voltages when entering and operating in programming modes and, as a consequence, has a weak drive strength as compared to regular I/O pins. See the figures for ATtiny24A: From Figure 3-22 on page 21 to Figure 3-25 on page 23. The figures for ATtiny44A: From Figure 3-67 on page 44 to Figure 3-70 on page 45.
These are test limits, accounting for leakage currents of the test environment. Actual device leakage currents are lower.
Values are with an external clock using methods described in “Minimizing Power Consumption”. Power reduction is enabled (PRR = 0xFF), and there is no I/O drive.
BOD disabled.
