SN74GTLP21395DGVR

Translators, Level Shifters Overview

The SN74GTLP21395DGVR is a dual 1-bit LVTTL-to-GTLP bus transceiver in a 20-pin TVSOP package. It operates at VCC levels of 3.15V to 3.45V with an operating temperature range of -40°C to +85°C. The device features adjustable edge-rate control (ERC) for optimizing signal integrity and includes TI-OPC circuitry to limit ringing. It supports live insertion via Ioff, power-up 3-state, and BIAS VCC functions.

Translators, Level Shifters Feature Summary

• Provides bidirectional translation between LVTTL logic levels and GTLP backplane signals
• Features split LVTTL port with separate input and output pins for feedback path monitoring
• Includes selectable polarity control for true or complementary data transmission modes
• Supports hot-insertion applications through dedicated precharge and high-impedance circuitry

Translators, Level Shifters Applications

• Primary and secondary clock distribution in parallel backplane systems
• High-speed interface between cards operating at LVTTL levels and GTLP backplanes
• Integration with Texas Instruments 3.3-V 1394 backplane physical-layer controllers
• Multislot parallel backplane applications requiring individual output-enable controls

Translators, Level Shifters Procurement Notes

Verify the specific DGV suffix indicates the TVSOP-20 package configuration. Confirm that the component meets RoHS compliance standards as specified in the ordering information. Ensure the supply voltage and termination requirements align with the GTLP standard specifications before integration into the design.

Translators, Level Shifters Selection Notes

Select this component when designing interfaces requiring both LVTTL and GTLP compatibility with diagnostic feedback capabilities. The adjustable edge-rate control allows optimization for varying backplane loads. Consider the TVSOP package constraints for PCB layout and thermal management during the selection process.

Translators, Level Shifters Part Context

This device belongs to the SN74GTLP series of high-drive bus transceivers designed for robust backplane communication. It complements other GTLP components by providing specific polarity control and feedback features not available in standard single-direction translators. The part is intended for use in complex digital systems requiring reliable high-speed data transfer.

Translators, Level Shifters Replacement Considerations

SN74GTLP21395DW and SN74GTLP21395PWR are functionally equivalent parts offering the same electrical characteristics in SOIC-20 and TSSOP-20 packages respectively.
