80C51 8-bit microcontroller family with extended memory
c) Maximum total IOL for all outputs: 71 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 conditions.
[9] ALE is tested to VOH1, except when ALE is off then VOH is the voltage specification.
[10] Pin capacitance is characterized but not tested.
10. Dynamic characteristics

Tamb = 0 °C to +70 °C for commercial unless otherwise specified. Formulae including tCLCL assume oscillator signal with
50/50 duty cycle.[1][2][3]
