Product Description
Pericom Semiconductors GTLP series of logic circuits are produced
using the Companys advanced 0.5 micron CMOS technology,
achieving industry leading performance.
The GTLP6C816 is a clock driver that provides TTL to GTLP signal
level translation (and vice versa). The device provides a high-speed
interface between cards operating at TTL logic levels and a backplane
operating at GTLP logic levels. High-speed backplane operation is
a direct result of GTLPs reduced output swing (<1V), reduced input
threshold levels, and output edge-rate control which minimizes bus
settling times.
Pericoms GTLP has internal edge-rate control. Its function is similar
to BTL or GTL but with different output levels and receiver threshold.
GTLP output low voltage is typically less than 0.5V, the output level
HIGH is 1.5V and the receiver threshold is 1.0V.
