1. Input or I/O leakage current is measured with the pin configured as an input or as an I/O with the output driver tri-stated. It is not measured
with the output driver active. Bus maintenance circuits are disabled.
2. T_A 25°C, f = 1.0MHz.
3. Please refer to V_IL and V_IH in the sysIO Single-Ended DC Electrical Characteristics table of this document.
4. When V_IH is higher than V_CCIO, a transient current typically of 30ns in duration or less with a peak current of 6mA can occur on the high-to-
low transition. For true LVDS output pins in MachXO2-640U, MachXO2-1200/U and larger devices, V_IH must be less than or equal to V_CCIO.
5. With bus keeper circuit turned on. For more details, refer to TN1202, MachXO2 sysIO Usage Guide.
