File Size : 116 KB Manufacturer:85 Description:The SN74GTLP22034 is a high-drive, 8-bit, three-wire registered transceiver that provides true LVTTL-to-GTLP and GTLP-to-LVTTL signal-level translation. The device allows for transparent, latched, and flip-flop modes of data transfer with separate LVTTL input and LVTTL output pins, which provides a feedback path for control and diagnostics monitoring, the same functionality as the SN74FB2033, but with true logic. The device provides a high-speed interface between cards operating at LVTTL logic levels and a backplane operating at GTLP signal levels. High-speed (about three times faster than standard LVTTL or TTL) backplane operation is a direct result of GTLPs reduced output swing (<1 V), reduced input threshold levels, improved differential input, OEC circuitry, and TI-OPC circuitry. Improved GTLP OEC and TI-OPC circuits minimize bus-settling time and have been designed and tested using several backplane models. The high drive allows incident-wave switching in heavily loaded backplanes with equivalent load impedance down to 11 Ω.
