2.5 V GTL
Gunning Transceiver Logic is a high-speed bus standard (JESD8-3). It provides a differential amplifier
input buffer and an open-drain output buffer. The VCCI pin should be connected to 2.5 V.

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.
5. Output drive strength is below JEDEC specification.
