MC100ELT23DT

Translators, Level Shifters Overview

The MC100ELT23DT is a mixed-signal voltage level translator manufactured by onsemi, designed to convert differential LVPECL or LVDS signals into LVTTL logic levels. It operates with a single 3.3V supply and features two independent channels within an 8-pin TSSOP package. The device provides non-inverting translation with a propagation delay of approximately 2.5 ns. It supports a wide operating temperature range from -40°C to +85°C and includes internal pull-down resistors to manage unused inputs.

Translators, Level Shifters Feature Summary

• Converts differential LVPECL or LVDS input signals directly to LVTTL output levels
• Provides dual-channel configuration for simultaneous signal translation
• Integrates internal pull-down resistors to simplify circuit design and reduce external component count

Translators, Level Shifters Applications

• Interfacing high-speed differential clock sources with TTL-based digital logic
• Level shifting in data acquisition systems requiring LVDS to LVTTL conversion
• Signal translation in telecommunications equipment utilizing ECL family standards

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DT' corresponds to the TSSOP-8 package variant when sourcing. Confirm RoHS compliance status as manufacturing processes may update environmental declarations over time. Check moisture sensitivity level (MSL) ratings prior to surface mount assembly to ensure proper handling during reflow soldering. Validate that the required propagation delay meets system timing constraints.

Translators, Level Shifters Selection Notes

Select this component when interfacing 3.3V differential LVPECL or LVDS drivers with LVTTL receivers. Ensure the application requires unidirectional translation from differential inputs to single-ended TTL outputs. Consider the 8-TSSOP package dimensions for PCB layout compatibility. Verify that the 3.3V supply voltage aligns with the target LVTTL logic family requirements.

Translators, Level Shifters Part Context

This part belongs to the MC100ECL/100ELT series of high-speed ECL-compatible logic devices. It serves as a specialized interface solution bridging the gap between low-voltage differential signaling standards and traditional transistor-transistor logic families. The device is part of onsemi's portfolio focused on maintaining signal integrity across different voltage domains in high-frequency applications.

Translators, Level Shifters Replacement Considerations

The SN65LVELT23 from Texas Instruments offers similar functionality as a dual differential LVPECL/LVDS to LVTTL translator. Verify pinout compatibility and electrical specifications before substitution.
