SN65LVELT23D

Translators, Level Shifters Overview

The SN65LVELT23D is a dual differential translator manufactured by Texas Instruments, designed to convert signals from 3.3V LVPECL or LVDS inputs to LVTTL outputs. It supports data rates up to 600 Mb/s with a maximum propagation delay of 900 ps. The device operates on a single 3.3 V supply within a voltage range of 3.0 V to 3.6 V and draws a typical operating current of 18 mA. Packaged in an 8-pin SOIC (D) case, it functions reliably across an industrial temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Provides unidirectional translation between differential LVPECL/LVDS logic families and single-ended LVTTL standards.
• Supports high-speed signal conversion with a maximum data rate of 600 Mb/s for reliable digital communication.
• Integrates two independent channels within a compact surface-mount package for space-constrained designs.

Translators, Level Shifters Applications

• Interfacing high-speed clock distribution networks using LVPECL sources with LVTTL-based processing units.
• Level shifting in telecommunications equipment requiring LVDS to LVTTL protocol conversion.
• Digital signal processing systems bridging differential input stages with standard TTL logic controllers.

Translators, Level Shifters Procurement Notes

Verify the specific suffix against official documentation to confirm packaging type, as 'D' denotes tube packaging while 'DR' indicates tape and reel. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Ensure the procurement channel provides valid traceability for industrial-grade components intended for harsh environments.

Translators, Level Shifters Selection Notes

Select this component when interfacing 3.3V differential sources directly with LVTTL loads without external pull-up resistors. Consider the 600 Mb/s limit for bandwidth requirements; higher speeds may require alternative translators. Evaluate the SOIC-8 footprint constraints against available PCB real estate compared to smaller alternatives like DGK packages.

Translators, Level Shifters Part Context

Part of the SN65LVELT series focusing on mixed-signal translation. This model specifically addresses the need to bridge the gap between low-voltage positive emitter-coupled logic and transistor-transistor logic families in mixed-voltage system architectures.

Translators, Level Shifters Replacement Considerations

The SN65LVELT22D serves as a functional substitute but translates in the opposite direction (LVTTL to LVPECL). Verify pin compatibility and signal flow direction before swapping. No direct reverse-direction equivalents are confirmed in the provided source material.
