Military ProASIC3/EL DC and Switching Characteristics
SSTL2 Class II
Stub-Speed Terminated Logic for 2.5 V memory bus standard (JESD8-9). Military ProASIC3E devices
support Class II. This provides a differential amplifier input buffer and a push-pull output buffer.

Notes:
1. I_IL is the input leakage current per I/O pin over recommended operating conditions where –0.3 V < VIN < VIL.
2. II_H 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 125°C junction temperature.
