100LVELT22MX

Overview

The MC100LVELT22MX is a unidirectional mixed-signal translator manufactured by Fairchild Semiconductor. It converts dual LVTTL or LVCMOS inputs to differential LVPECL outputs. The device operates within a supply voltage range of 3.0 V to 3.8 V. It features a propagation delay of 600 ps and functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in an 8-pin SOIC package.

Feature Summary

• Converts single-ended LVTTL/LVCMOS signals to differential LVPECL levels
• Provides dual-channel translation capability for high-speed interfaces
• Operates with standard 3.3 V power supplies

Applications

• Level shifting between low-voltage logic families and ECL-based systems
• High-speed data interface translation in telecommunications equipment
• Signal conversion in test and measurement instrumentation

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor assets were acquired by onsemi. Confirm the specific suffix 'MX' corresponds to the SOIC-8 package variant. Ensure RoHS compliance status matches current regulatory requirements. Check for obsolescence notices or lifecycle changes affecting long-term availability.

Selection Notes

Select this component when interfacing 3.3 V digital logic with LVPECL receivers. The dual-channel architecture supports parallel data paths. Verify that the input signal swing aligns with LVTTL or LVCMOS standards. Ensure the PCB layout accommodates the differential output requirements for impedance matching.
