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