Notes
1. All V_DD and V_SS connections must be made externally to the same power supply.
2. Equivalent to discharging a 100 pF capacitor via a 1.5 kΩ series resistor with a rise time of 15 ns.
3. Equivalent to discharging a 200 pF capacitor via a 2.5 µH series inductor.
9 CHARACTERISTICS
V_DD = 4.75 to 5.25 V; V_SS = 0 V; T_amb = 0 to +70 °C; unless otherwise specified.
