2.4.1 GTL+

Gunning Transceiver Logic Plus (GTL+) is a high-speed bus standard (JESD8-3). It requires a differential amplifier input buffer and an Open Drain output buffer. The VCCI pin should be connected to 2.5V or 3.3V. Note that 2.5V GTL+ is not supported across the full military temperature range.

The following table lists the DC input and output levels of GTL+.
