HSTL Class II
High-Speed Transceiver Logic is a general-purpose high-speed 1.5 V bus standard (EIA/JESD8-6). Fusion devices support
Class II. This provides a differential amplifier input buffer and a push-pull output buffer.

Drive Strength Min., V
15 mA
Notes:
1. Currents are measured at high temperature (100°C junction temperature) and maximum voltage.
2. Currents are measured at 85°C junction temperature.
3. Output drive strength is below JEDEC specification.
