100ELT22MX

Overview

The 100ELT22MX is a mixed-signal translator manufactured by Fairchild Semiconductor, operating from a single +5V supply. It functions as a unidirectional TTL to differential PECL translator featuring one circuit and two channels. The device is housed in an 8-SOIC package with a specified operating temperature range of -40°C to 85°C.

Feature Summary

• Converts TTL input signals to differential PECL outputs
• Operates on a single +5V power supply
• Provides two channels for improved performance

Applications

• System clock distribution networks requiring level translation
• High-speed digital interfaces converting logic families
• Differential signaling applications in telecommunications equipment

Procurement Notes

Verify the manufacturer designation, as Fairchild Semiconductor assets were acquired by ON Semiconductor. Confirm the specific suffix 'MX' corresponds to the 8-SOIC bulk packaging variant. Ensure the component meets RoHS compliance standards if required for your assembly process. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a unidirectional interface between TTL and PECL domains is required within a single-supply system. The dual-channel architecture supports simultaneous signal conversion. Verify that the output swing matches the receiving PECL circuitry requirements. Consider thermal management within the -40°C to 85°C operational envelope during design integration.

Part Context

This part belongs to the 100EL series of high-speed logic translators. It serves as a bridge between standard TTL logic levels and low-voltage differential signaling (PECL). The device simplifies board layout by eliminating external biasing components typically needed for PECL outputs.
