45 / 220 page ![]() ProASIC3 Flash Family FPGAs Revision 13 2-31 Single-Ended I/O Characteristics 3.3 V LVTTL / 3.3 V LVCMOS Low-Voltage Transistor–Transistor Logic (LVTTL) is a general-purpose standard (EIA/JESD) for 3.3 V applications. It uses an LVTTL input buffer and push-pull output buffer.

IIL is the input leakage current per I/O pin over recommended operation conditions where –0.3 V < VIN < VIL. 2. IIH is the input leakage current per I/O pin over recommended operating conditions VIH < VIN < VCCI. Input current is larger when operating outside recommended ranges 3. Currents are measured at 100°C junction temperature and maximum voltage. 4. Currents are measured at 85°C junction temperature. 5. Software default selection highlighted in gray.
