Description

The GTLP6C817 is a low drive clock driver that providesTTL to GTLP signal level translation (and vice versa). The GTLP6C817 provides a high speed interface between cardsoperating at TTL logic levels and a backplane operating atGTLP logic levels. High speed backplane operation is adirect result of GTLP's reduced output swing (<1V),reduced input threshold levels and output edge rate con-trol. The edge rate control minimizes bus settling time.GTLP is a Fairchild Semiconductor derivative of the Gun-ning Transceiver logic (GTL) JEDECstandard JESD8-3.

Fairchild's GTLP GTLP6C817 has internal edge-rate control and is pro-cess, voltage, and temperature (PVT) compensated. GTLP6C817's function is similar to BTL and GTL but with different outputlevels and receiver threshold. GTLP GTLP6C817 output LOW level istypically less than 0.5V, the output level HIGH is 1.5V andthe receiver threshold is 1.0V.
