95 / 212 page ![]() Military ProASIC3/EL Low Power Flash FPGAs Revision 3 2-81 HSTL Class II High-Speed Transceiver Logic is a general-purpose high-speed 1.5 V bus standard (EIA/JESD8-6). Military ProASIC3E devices support Class II. This provides a differential amplifier input buffer and a push-pull output buffer.

IIL is the input leakage current per I/O pin over recommended operating 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 125°C junction temperature. 5. Output drive strength is below JEDEC specification.
