Fusion Family of Mixed Signal FPGAs
SSTL3 Class II
Stub-Speed Terminated Logic for 3.3 V memory bus standard (JESD8-8). Fusion devices support Class
II. This provides a differential amplifier input buffer and a push-pull output buffer.

Notes:
1. 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 high temperature (100°C junction temperature) and maximum voltage.
4. Currents are measured at 85°C junction temperature.
