NOTES FOR DS80C323 AC ELECTRICAL CHARACTERISTICS:
All parameters apply to both commercial and industrial temperature range operation unless otherwise
noted. AC timing characteristics valid for oscillator frequency > 16 MHz.
1. All signals rated over operating temperature at 33 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 30 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 variations.
5. Address is held in a weak latch until over driven by external memory.
