OSCILLATOR CHARACTERISTICS
GENERAL INTERFACE ELECTRICAL CHARACTERISTICS
Note: 1. The leakage currents are generally very small, <1nA. The value given here, 1mA, ia amaximum that can occur after an Electrostatic
Stress on the pin.
2. Human Body Model.
LOW VOLTAGE CMOS INTERFACE DC ELECTRICAL CHARACTERISTICS
Note: 1. Takes into account 200mV voltage drop in both supply lines.
2. X is the source/sink current under worst case conditions and is reflected in the name of the I/O cell according to the drive capability.
LOW VOLTAGE TTL INTERFACE DC ELECTRICAL CHARACTERISTICS
Note: 1. TTL specifications only apply to the supply voltage range Vdd = 3.0V to 3.6V
2. Takes into account 200mV voltage drop in both supply lines.
3. X is the source/sink current under worst case conditions and is reflected in the name of the I/O cell according to the drive capability.
