Stresses greater than those listed under ABSOLUTE MAXIMUM RAT- INGS 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. No terminal voltage may exceed VCC by +0.5V unless otherwise noted. 2. Input and VCC terminals only. 3. Outputs and I/O terminals only. 2539 lnk 03 Symbol Parameter(1) Conditions Typ. Max. Unit CIN Input Capacitance VIN = 0V 6 10 pF COUT Output Capacitance VOUT = 0V 8 12 pF 2539 lnk 04 NOTE: 1.
