TRANSCEIVER
DESCRIPTION:
The GTLP16612 is an 18-bit universal bus transceiver. It provides
signal level translation, from TTL to GTLP, for applications requiring a high-
speed interface between cards operating at TTL logic levels and back-
planes 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 Gun-
ning 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 threshold is 1V.
