description
The SN74GTLPH16612 is a medium-drive, 18-bit UBT (universal bus transceiver) that provides
LVTTL-to-GTLP and GTLP-to-LVTTL signal-level translation. It allows for transparent, latched, clocked, or
clock-enabled modes of data transfer. This device provides a high-speed interface between cards operating at
LVTTL logic levels and backplanes operating at GTLP signal levels. High-speed (about two times faster than
standard LVTTL or TTL) backplane operation is a direct result of the reduced output swing (
<
1 V), reduced input
threshold levels, and OEC
(output edge control). These improvements minimize bus settling time and have
been designed and tested using several backplane models.
