Military ProASIC3/EL DC and Switching Characteristics

2-80

Revision 3

HSTL Class I

High-Speed Transceiver Logic is a general-purpose high-speed 1.5 V bus standard (EIA/JESD8-6).

Military ProASIC3E devices support Class I. 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 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.
