SY10ELT21ZC-TR

Translators, Level Shifters Overview

The SY10ELT21ZC-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 Low Voltage Positive ECL input levels. The device utilizes a small outline 8-lead SOIC package with flow-through pinouts, designed for applications demanding minimal space, low power consumption, and cost efficiency. It supports differential, single-ended, or AC-coupled interfaces. Under open input conditions, the device biases outputs to provide stability, forcing the Q output low.

Translators, Level Shifters Feature Summary

• Translates differential LVPECL signals to LVTTL levels using a single 3.3V supply
• Features flow-through pinouts in an 8-lead SOIC package for compact design
• Provides added stability under open input conditions by biasing outputs

Translators, Level Shifters Applications

• Clock signal translation where minimal space is critical
• Data signal translation requiring low power operation
• Applications necessitating low cost voltage level conversion

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'ZC' against official Microchip documentation to confirm lead-free status and RoHS compliance details. Ensure the operating temperature range matches your system requirements, as industrial grades may vary. Confirm the package type is indeed SOIC-8 and check for any recent product change notifications that might affect availability or specifications.

Translators, Level Shifters Selection Notes

Select this component when translating LVPECL sources to LVTTL destinations within space-constrained designs. It is suitable for systems requiring a single 3.3V supply rail without additional negative voltages. Consider the propagation delay and power consumption characteristics relative to other translators in the Precision Edge family if higher speed or different packaging is needed.

Translators, Level Shifters Part Context

This part belongs to the SY10/100ELT21L series of Precision Edge translators. These devices are designed for high-speed clock and data translation. The series emphasizes low power and small form factor, making it distinct from standard ECL translators that may require dual supplies. It serves as a bridge between high-speed differential logic families and standard TTL-compatible inputs.

Translators, Level Shifters FAQ

How does the device handle open input conditions?

Under open input conditions, the /D output is biased at a VCC/2 voltage level, while the D input is pulled to ground. This configuration forces the Q output low to provide added circuit stability.

What interface options are supported by the SY10ELT21ZC-TR?

The device allows for differential, single-ended, or AC-coupled interfaces to the input pins, providing flexibility in system integration.
