SN74GTLP1394DGVR

Translators, Level Shifters Overview

The SN74GTLP1394DGVR is a 2-bit LVTTL-to-GTLP bus transceiver in a 16-pin TVSOP package. It operates with a supply voltage (VCC) of 3.15 V to 3.45 V and supports an operating temperature range from -40°C to +85°C. The device provides bidirectional signal translation between LVTTL logic levels and GTLP backplane levels, featuring adjustable edge-rate control for optimized data transfer. It includes split LVTTL ports for feedback paths and selectable polarity for true or complementary output modes.

Translators, Level Shifters Feature Summary

• Provides bidirectional interface between GTLP signal levels and LVTTL logic levels
• Features split LVTTL port providing a dedicated feedback path for control and diagnostics monitoring
• Includes adjustable edge-rate control input to select GTLP rise and fall times for optimal signal integrity
• Supports live insertion via Ioff, power-up 3-state, and BIAS VCC circuitry

Translators, Level Shifters Applications

• High-speed interface between cards operating at LVTTL logic levels and backplanes operating at GTLP signal levels
• Interface with Texas Instruments 1394 backplane physical-layer controllers
• Transmission of IEEE 1394 backplane serial bus across parallel backplanes
• Providing multiple single-bit clocks or ATM read/write clock in multislot parallel backplane applications

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the tape-and-reel packaging format and the TVSOP-16 physical package dimensions. Confirm that the component meets RoHS compliance standards as indicated in manufacturer documentation. Ensure compatibility with the required VTT termination voltage and VREF reference voltage settings for the target GTLP application environment.

Translators, Level Shifters Selection Notes

Select this component when a high-drive, 2-bit transceiver is required for translating between LVTTL and GTLP domains. The device is suitable for designs needing separate input and output pins for diagnostic feedback. Consider the adjustable edge-rate control feature if system signal integrity requires optimization of rise and fall times against distributed backplane loads.

Translators, Level Shifters Part Context

This device belongs to the SN74GTLP1394 series of bus transceivers. It is specifically engineered to support the Texas Instruments 1394 backplane physical layer standard. The technology utilizes OEC and TI-OPC circuitry to limit ringing and improve signal integrity on unevenly loaded backplanes compared to standard LVTTL interfaces.
