Capacitance(1) (TA = +25°C, f = 1.0MHz)
Recommended DC Operating
Conditions
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. VTERM must not exceed VDD + 0.3V for more than 25% of the cycle time or 10ns
maximum, and is limited to < 20mA for the period of VTERM > VDD + 0.3V.
NOTES:
1. This parameter is determined by device characterization but is not production
tested.
2. COUT also references CI/O.
NOTE:
1. This is the parameter TA. This is the "instant on" case temperature.
NOTES:
1. VIL > -1.5V for pulse width less than 10ns.
2. VTERM must not exceed VDD + 0.3V.
DC Electrical Characteristics Over the Operating
Temperature and Supply Voltage Range (VDD = 3.3V ± 0.3V)
NOTE:
1. At VDD < 2.0V leakages are undefined.
