SN74GTLP1394
2-BIT LVTTL-TO-GTLP ADJUSTABLE-EDGE-RATE BUS TRANSCEIVER
WITH SPLIT LVTTL PORT, FEEDBACK PATH, AND SELECTABLE POLARITY
SCES286F – OCTOBER 1999 – REVISED APRIL 2005
FEATURES
• TI-OPC™ Circuitry Limits Ringing on
Unevenly Loaded Backplanes
• OEC™ Circuitry Improves Signal Integrity and
Reduces Electromagnetic Interference
• Bidirectional Interface Between GTLP Signal
Levels and LVTTL Logic Levels
• Split LVTTL Port Provides a Feedback Path
for Control and Diagnostics Monitoring
• LVTTL Interfaces Are 5-V Tolerant
• High-Drive GTLP Outputs (100 mA)
• LVTTL Outputs (–24 mA/24 mA)
• Variable Edge-Rate Control (ERC) Input
Selects GTLP Rise and Fall Times for Optimal
Data-Transfer Rate and Signal Integrity in
Distributed Loads
• I_off, Power-Up 3-State, and BIAS V_CC Support
Live Insertion
• Polarity Control Selects True or
Complementary Outputs
• Latch-Up Performance Exceeds 100 mA Per
JESD 78, Class II
• ESD Protection Exceeds JESD 22
– 2000-V Human-Body Model (A114-A)
