SN74GTLPH1655 is a high-drive 16-bit universal bus transceiver (UBT) that provides LVTTL-to-GTL+ and GTL+-to-LVTTL signal-level translation. It is partitioned as two 8-bit transceivers and allows for transparent, latched, and clocked modes of data transfer similar to the ’16501 function. The device provides high-speed interface between cards operating ata LVTTL logic levels and a backplane operating at GTL+ signal levels. High-speed (about two times faster than standard LVTTL or TTL) backplane operation is a direct result of GTLP
