GTLP FAMILY SUMMARY
Primary features of the GTLP devices:
• 3.3-V V
CC
operation with 5-V tolerant LVTTL I/Os, which allows the devices to act
as 5-V TTL-to-GTL/GTL+, as well as 3.3-V LVTTL-to-GTL/GTL+, translators.
• Optimized OEC circuitry allows clock frequencies of >80 MHz in high-performance,
heavily loaded backplane applications.
• Fully supports live insertion with backplane precharge circuitry
• CMOS construction for low-static power consumption
• A-port (LVTTL side) balanced drive of ±24 mA
• B-port (GTL/GTL+ side) drive of 50 mA or 100 mA, which allows the designer
flexibility in matching the device to backplane length, slot spacing, and termination
resistance
• Each data sheet provides both the lumped-load specified data and
resistive/inductive/capacitive (RLC) network data for the designer. The RLC data
more closely approximates the device response in a distributed load.
• The SN74GTLP1394 is designed specifically to work with the TSB14AA1 (1394
backplane physical-layer controller) in multiple-slot backplane applications.
