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. TA 25°C, f = 1.0MHz. 3. Please refer to VIL and VIH in the sysIO Single-Ended DC Electrical Characteristics table of this document. 4. When VIH is higher than VCCIO, 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, VIH must be less than or equal to VCCIO. 5. With bus keeper circuit turned on. For more details, refer to TN1202, MachXO2 sysIO Usage Guide. |
