Notes: 4. Specifications guaranteed by characterization and not production testing.
5. Refer to V/I curves in Figure 1. Specification does not apply to CLK and RST# signals. Switching Current
High specification does not apply to SERR# and INTA# which are open drain outputs.
6. Cumulative edge rate across specified range. Rise slew rates do not apply to open drain outputs.
7. Equation A: IOH = 11.9 * (Vout - 5.25) * (Vout + 2.45) for 3.3 V > Vout > 3.1 V
8. Equation B: IOL = 78.5 * Vout * (4.4 - Vout) for 0 V < Vout < 0.71 V

for 3.3V > Vout > 3.1V
IOL = 78.5*Vout*(4.4-Vout)
for 0V < Vout < 0.71V
