SY100S391JZ

Translators, Level Shifters Overview

The SY100S391JZ is a hex TTL-to-PECL translator manufactured by Microchip Technology. It operates from a single +5V supply and provides differential PECL outputs. The device features six data inputs (D0–D5) and corresponding true and inverting outputs (Q0–Q5). A common enable input (E) controls output states. It is housed in a 28-pin PLCC package.

Translators, Level Shifters Feature Summary

• Translates TTL logic levels to PECL logic levels using only a single +5V power supply
• Provides differential true and inverting outputs for flexible line driving or translation modes
• Includes a common enable input that holds all outputs in defined states when activated

Translators, Level Shifters Applications

• Mixed PECL/TTL applications with limited power supply options
• Converting TTL signals to high-speed PECL systems
• Differential line driver implementations requiring ground isolation

Translators, Level Shifters Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND). Confirm lead finish specifications, noting that the JZ suffix indicates a matte tin Pb-free bar-line indicator. Ensure compatibility with existing 28-pin PLCC footprints during procurement planning.

Translators, Level Shifters Selection Notes

Select this component for designs requiring direct TTL-to-PECL translation without dual supplies. Verify that the commercial temperature range of 0°C to +85°C meets system requirements. Consider the propagation delay characteristics when designing high-speed signal paths.

Translators, Level Shifters Part Context

This part belongs to the SY100S360 series of clock generators and support products. It serves as a specialized interface solution within the broader portfolio of high-speed logic ICs designed for mixed-voltage digital systems.

Translators, Level Shifters Replacement Considerations

The datasheet notes functional and pinout compatibility with the Fairchild F100K. Evaluate this alternative if sourcing the current part is restricted due to its NRND status.
