NOTES FOR AC ELECTRICAL CHARACTERISTICS:
All parameters apply to both commercial and industrial temperature range operation unless otherwise
noted. All signals rated over operating temperature. All signals characterized with load capacitance of 80
pF except Port 0, ALE, PSEN , RD and WR with 100 pF. Interfacing to memory devices with float times
(turn off times) over 25 ns may cause contention. This will not damage the parts, but will cause an
increase in operating current. Specifications assume a 50% duty cycle for the oscillator. Port 2 and ALE
timing will change in relation to duty cycle variation.
