The SN74GTL16616DL is a 17-bit UBT™ transceiver that provides LVTTL-to-GTL/GTL+ and GTL/GTL+-to-LVTTL signal-level translation. Combined D-type flip-flops and D-type latches allow for transparent, latched, clocked, and clocked-enabled modes of data transfer identical to the ‘16601 function.
Additionally, this device provides for a copy of CLKAB at GTL/GTL+ signal levels (CLKOUT) and conversion of a GTL/GTL+ clock to LVTTL logic levels (CLKIN). This device provides an interface between cards operating at LVTTL logic levels and a backplane operating at GTL/GTL+ signal levels.
Higher-speed operation is a direct result of the reduced output swing (<1 V), reduced input threshold levels, and OEC circuitry.
