1. VIL (min.) = –1.0V for pulse width less than tCYC/2, once per cycle.
2. VIH (max.) = +6.0V for pulse width less than tCYC/2, once per cycle.
3. VDD needs to be ramped up smoothly to the operating level. If there are any
glitches on VDD that cause the voltage level to drop below 2.0 volts then the
device needs to be reset by holding VDD to 0.0 volts for a minimum of 100 ms.

NOTES:
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. VDD and Input terminals only.
3. I/O terminals.
4. During production testing, the case temperature equals the ambient temperature.
