Notes
1. All V_DD (and V_pos) connections and V_SS (and V_neg) 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 = 3.0 to 3.6 V; V_SS = 0 V; T_amb = −10 to +70 °C; unless otherwise specified.
