AC Electrical Characteristics - Timing Parameter Measurement Voltage Levels* -
ground (VSS) unless otherwise stated.
* Timing for output signals is based on the worst case result of the combination of TTL and CMOS thresholds.
AC Electrical Characteristics - Motorola Microprocessor Timing*
‡Typical figures are at 25°C and are for design aid only: not guaranteed and not subject to production testing.
Note 1. High impedance is measured by pulling to the appropriate rail with R
