(1)

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 500 lfpm. Electrical parameters are assured only over the declared operating

temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit values are

applied individually under normal operating conditions and not valid simultaneously.

(2)

VEE can vary ±0.3 V

(3)

Maximum switching frequency measured at output amplitude of 300 mVpp.

(4)

Within-device skew is defined as identical transitions on similar paths through a device.

(5)

Device-Device Skew is defined as identical transitions at identical Vcc levels.

(6)

Duty cycle skew is the difference between a tPLH and tPHL propagation delay through a device.

(7)

VPP(min) is the minimum input swing for which AC parameters are assured.
