noise pulse on the ALE line may exceed 0.45V with maxi VOL peak 0.6V. A Schmitt
Trigger use is not necessary.
5. Under steady state (non-transient) conditions, IOL must be externally limited as fol-
lows:
Maximum IOL per port pin: 10 mA
Maximum IOL per 8-bit port:
Port 0: 26 mA
Ports 1, 2 and 3: 15 mA
Maximum total IOL for all output pins: 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.
6. Operating ICC is measured with all output pins disconnected; XTAL1 driven with
T
CLCH, TCHCL = 5 ns, VIL = VSS + 0.5 V,
VIH = VCC - 0.5V; XTAL2 N.C.; EA = Port 0 = VCC; RST = VSS. The internal ROM runs
the code 80 FE (label: SJMP label). ICC would be slightly higher if a crystal oscillator
is used. Measurements are made with OTP products when possible, which is the
worst case.
