1. V IL > -1.5V for pulse width less than 10ns.

2. V TERM must not exceed Vcc + 10%.

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may

cause permanent damage to the device. This is a stress rating only and

functional operation of the device at these or any other conditions above those

indicated in the operational sections of this specification is not implied. Exposure

to absolute maximum rating conditions for extended periods may affect

reliability.

2. V TERM must not exceed Vcc + 10% for more than 25% of the cycle time or 10ns

maximum, and is limited to < 20mA for the period of V TERM > Vcc + 10%.
