NOTES FOR AC ELECTRICAL CHARACTERISTICS:
All parameters apply to both commercial and industrial temperature range operation unless otherwise noted.
1. All signals rated over operating temperature at 25 MHz.
2. All signals characterized with load capacitance of 80 pF except Port 0, ALE, PSEN, RD and WR at 100 pF.
Note that loading should be approximately equal for valid timing.
3. Interfacing to memory devices with float times (turn off times) over 35 ns may cause contention. This will not
damage the parts, but will cause an increase in operating current.
4. Specifications assume a 50% duty cycle for the oscillator. Port 2 timing will change with the duty cycle varia-
tions.
5. Address is held in a weak latch until over driven by external memory.
