SN74GTLP21395DWR

Translators, Level Shifters Overview

The SN74GTLP21395DWR is a dual 1-bit LVTTL-to-GTLP bus transceiver in a 20-pin SOIC package. It operates at VCC from 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 backplane signals and LVTTL logic levels with high-drive outputs.
• Features adjustable edge-rate control (ERC) input to select rise and fall times for optimal signal integrity.
• Includes TI-OPC circuitry to limit ringing on unevenly loaded backplanes and OEC circuitry to reduce electromagnetic interference.
• Supports live insertion through Ioff, power-up 3-state, and BIAS VCC circuitry.

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

Verify the specific ordering suffix 'DWR' corresponds to the tape and reel packaging variant of the SN74GTLP21395. Confirm that the component meets RoHS standards and matches the specified SOIC-20 package dimensions. Ensure compatibility with the required supply voltage range and temperature specifications for the target application environment before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when designing interfaces requiring translation between LVTTL and GTLP domains with individual output-enable controls. The split LVTTL port allows for diagnostics monitoring via a feedback path. Consider the adjustable edge-rate feature if system signal integrity requires optimization for distributed loads or specific data-transfer rates.
