SY100ELT21ZC-TR

Translators, Level Shifters Overview

The SY100ELT21ZC-TR is a single differential LVPECL-to-LVTTL translator manufactured by Microchip Technology. It operates on a single +3.3V power supply, requiring only VCC and ground connections due to its LVPECL input levels. The device features low skew and low power consumption, making it suitable for space-constrained designs. It utilizes a small outline 8-lead SOIC package with surface mount installation. The component supports flow-through pinouts and includes internal biasing mechanisms to ensure stability under open input conditions.

Translators, Level Shifters Procurement Notes

Verify the specific suffix ZC against official Microchip documentation to confirm package type and environmental compliance status. Confirm availability as distribution data may vary. Ensure the selected variant matches the required operating temperature range and RoHS specifications for the target application environment before procurement.

Translators, Level Shifters Selection Notes

Select this component when translating between LVPECL and LVTTL domains within a single 3.3V system. It is appropriate for applications prioritizing low propagation delay and reduced board space over multi-channel capabilities. Consider the 8-pin SOIC package constraints and verify that the load capacitance requirements are met by the downstream LVTTL inputs.

Translators, Level Shifters Part Context

This part belongs to the Precision Edge 100ELT series of voltage level translators. The series focuses on providing fast, low-power solutions for interfacing different logic families. The ELT21 specifically addresses the common need to bridge Low Voltage Positive ECL standards with TTL-compatible logic levels in modern embedded and communication hardware.

Translators, Level Shifters Replacement Considerations

Consult official substitution guides for equivalent single-channel LVPECL-to-LVTTL translators from the same manufacturer family. Verify pinout compatibility and electrical characteristics such as propagation delay and supply current before replacing.
