Advance Information
† See "Notes" following AC Electrical Characteristics tables.
AC Electrical Characteristics - Timing Parameter Measurement Voltage Levels* -
with respect to ground (V
* Supply voltage and operating temperature are as per Recommended Operating Conditions.
* Timing for input and output signals is based on the worst Chislehurst of the combination of TTL and CMOS thresholds.
* See Figure 10.
