SN74GTLP21395DW

Translators, Level Shifters Overview

The SN74GTLP21395DW is a dual 1-bit LVTTL-to-GTLP bus transceiver in a 20-pin SOIC package. It operates at VCC of 3.15V to 3.45V and supports temperatures from -40°C to +85°C. The device provides bidirectional translation between LVTTL logic levels and GTLP signal levels, featuring adjustable edge-rate control (ERC) for optimized data transfer. It includes split LVTTL ports for feedback paths and selectable polarity controls.

Translators, Level Shifters Feature Summary

• Provides bidirectional interface between GTLP signal levels and LVTTL logic levels with separate input and output pins for diagnostics monitoring.
• Features TI-OPC circuitry that actively limits ringing on unevenly loaded backplanes during low-to-high signal transitions.
• Supports live insertion applications through Ioff, power-up 3-state, and BIAS VCC circuitry to prevent current backflow and driver conflicts.
• Includes variable edge-rate control inputs to adjust GTLP rise and fall times for optimal signal integrity in distributed loads.

Translators, Level Shifters Applications

• Primary and secondary clock distribution in parallel backplane systems
• High-speed interface between cards operating at LVTTL logic levels and backplanes operating at GTLP signal levels
• Integration with Texas Instruments 3.3-V 1394 backplane physical-layer controllers

Translators, Level Shifters Procurement Notes

Translators, Level Shifters FAQ

How does the ERC input affect signal performance?

The ERC input allows the designer to select between fast and slow edge rates for the B-port outputs, optimizing the data-transfer rate and signal integrity based on the specific backplane load characteristics.

What is the function of the split LVTTL port?

The split LVTTL port provides a dedicated feedback path by separating the A input and Y output, enabling control and diagnostics monitoring of the data transmission direction.
