SY100ELT25ZG

Translators, Level Shifters Overview

The SY100ELT25ZG is a differential ECL-to-TTL translator manufactured by Microchip Technology. It operates with VCC from 4.5V to 5.5V and VEE from -4.2V to -5.5V. The device provides a typical propagation delay of 2.6ns, with maximum delays of 3.6ns across the operating temperature range of -40°C to +85°C. It features 24mA TTL outputs and accepts differential ECL inputs. The component is housed in an 8-pin SOIC package.

Translators, Level Shifters Feature Summary

• Translates differential ECL signals to standard TTL logic levels
• Supports single-ended input mode via VBB pin configuration
• Provides high-drive 24mA TTL outputs for reliable interfacing

Translators, Level Shifters Applications

• Interfacing ECL clock sources to TTL-based digital systems
• Signal translation in mixed-voltage logic circuits
• High-speed data path conversion between ECL and TTL domains

Translators, Level Shifters Procurement Notes

Verify the specific suffix ZG indicates Pb-Free packaging with NiPdAu finish when sourcing replacements. Confirm that the industrial temperature grade (-40°C to +85°C) matches system requirements. Check current availability status as older Micrel/Microchip logic families may have limited stock or obsolescence notices.

Translators, Level Shifters Selection Notes

Select this component when converting differential ECL signals to TTL without requiring complex external biasing networks. The flow-through pinout simplifies PCB layout compared to other translators. Ensure power supplies meet the specified VCC and VEE ranges to maintain signal integrity and timing specifications.

Translators, Level Shifters Part Context

This part belongs to the SY100ELT series of voltage level translators originally developed by Micrel, Inc., now under Microchip Technology. The series focuses on bridging legacy ECL standards with modern TTL interfaces in high-performance computing and telecommunications equipment.
