NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. Unused inputs without Bus-Hold must be held HIGH or LOW.
The GTLP16612 is an 18-bit universal bus transceiver. It provides signal level translation, from TTL to GTLP, for applications requiring a highspeed interface between cards operating at TTL logic levels and backplanes operating at GTLP logic levels. GTLP provides reduced output swing (<1V), reduced input threshold levels, and output edge-rate control to minimize signal setting times. The GTLP16612 is a derivative of the Gunning Transceiver Logic (GTL) JEDEC standard JESD8-3 and incorporates internal edge-rate control, which is process, voltage, and temperature (PVT) compensated.
GTLP output low voltage is less than 0.5V. The output high is 1.5V, and the receiver IDT74GTLP16612 threshold is 1V.
