NOTES:
1. Parameters are valid over operating temperature range unless otherwise specified.
2. Load capacitance for port 0, ALE, and PSEN = 100pF, load capacitance for all other outputs = 80pF.
3. Interfacing the SC80C31/51 to devices with float times up to 45ns is permitted. This limited bus contention will not cause damage to Port 0
drivers.
4. Variable clock is specified for oscillator frequencies greater than 16MHz to 33MHz. For frequencies equal or less than 16MHz, see 16MHz
