description  
The SN74GTLP21395 is two 1-bit, high-drive, 3-wire bus transceivers that provide LVTTL-to-GTLP and  
GTLP-to-LVTTL signal-level translation for applications, such as primary and secondary clocks, that require  
individual output-enable and true/complement controls. The device allows for transparent and inverted  
transparent modes of data transfer with separate LVTTL input and LVTTL output pins, which provide a feedback  
path for control and diagnostics monitoring. The device provides a high-speed interface between cards  
operating at LVTTL logic levels and a backplane operating at GTLP signal levels and is designed especially to  
work with the Texas Instruments 3.3-V 1394 backplane physical-layer controller. High-speed (about three times  
faster than standard LVTTL or TTL) backplane operation is a direct result of GTLP reduced output swing (<1 V),  
reduced input threshold levels, improved differential input, OEC circuitry, and TI-OPC circuitry. Improved  
GTLP OEC and TI-OPC circuitry minimizes 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.  
The Y outputs, which are designed to sink up to 12 mA, include equivalent 26-Ω resistors to reduce overshoot  
and undershoot.

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
