* Timing for output signals is based on the worst case result of the combination of TTL and CMOS thresholds.

Figure 27 - Timing Parameter Measurement Voltage Levels

‡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 RL, with timing corrected to cancel time taken to discharge CL.

AC Electrical Characteristics - Timing Parameter Measurement Voltage Levels* - Voltages are with respect to

ground (VSS) unless otherwise stated.
