are guaranteed by design and not product tested. AC electrical characteristics assume 50% duty cycle for the oscillator, and
are not 100% tested but are guaranteed by design. All signals characterized with load capacitance of 80pF except Port 0, ALE,
PSEN, and WR with 100pF. Interfacing to memory devices with float times (turn-off times) over 25ns can cause contention.
This does not damage the parts, but rather causes an increase in operating current. Port 2 and ALE timing changes in relation
to duty cycle variation.
All parameters apply to both commercial and industrial temperature operation unless otherwise noted. Specifications to -40C
Address is held in a weak latch until overdriven by external memory.
