DC Characteristics
The DC electrical characteristics define the input operating conditions for proper
operation and the output responses to applied DC signals and switch characteristics over
specified voltage and temperature ranges. The DC electrical characteristics are specified
within the recommended operating conditions including operating temperature and power
supply range as stated in this data sheet. Table 34 outlines the C-3e NP DC characteristics.

All voltages are relative to Ground unless otherwise indicated.
Each control input pin has a capacitance associated with it. The capacitance at the control
input is due to the package and the input circuitry connected to the pin. Capacitance is
based on these conditions: TA = 25°C; VDD33 = 3.3V; f = 1MHz. Table 35 provides
capacitance data.
