Notes:
12. The device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit board with
maintained transverse airflow greater than 500lfpm. Electrical parameters are guaranteed only over the declared operating temperature range.
Functional operation of the device exceeding these conditions is not implied. Device specifications limit values are applied individually under normal
operating conditions and not valid simultaneously.
13. Measured using a 750mV source, 50% duty cycle clock source, all loading with 50 to VCC–2V.
14. VOL and VOH specifications not guaranteed for fMAX testing
15. Skew is measured between outputs under identical transitions and conditions on any one device.
16. Device-to-device skew for identical transitions at identical VCC levels.
