SY100S391JZ-TR

Translators, Level Shifters Overview

The SY100S391JZ-TR is a low-power 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), an enable input (E), true outputs (Q0–Q5), and inverting outputs (Q0–Q5). It is housed in a 28-pin PLCC package with a commercial operating temperature range of 0°C to +85°C.

Translators, Level Shifters Feature Summary

• Translates TTL logic levels to PECL logic levels using only a single +5V power supply
• Provides differential outputs that function as inverting/non-inverting translators or differential line drivers
• Features high common mode rejection to overcome voltage gradients between separate ground systems

Translators, Level Shifters Applications

• Mixed PECL/TTL applications restricted to a single +5V supply
• Converting TTL logic signals to 100K logic levels
• Differential line driving in mixed-signal environments

Translators, Level Shifters Procurement Notes

Verify the component manufacturer, as Micrel was acquired by Microchip Technology. Confirm the specific ordering suffix matches the required tape and reel packaging and lead finish specifications for your assembly process.

Translators, Level Shifters Selection Notes

Select this component when a system requires translating TTL inputs to PECL outputs while constrained to a single +5V supply rail. Ensure the design accommodates the 28-pin PLCC package dimensions and the specified commercial temperature range.

Translators, Level Shifters Part Context

This part belongs to the SY100S391 family of low-power hex TTL-to-PECL translators. It is functionally and pinout compatible with the Fairchild F100K. The device is categorized under clock generators and support products within the broader logic IC portfolio.

Translators, Level Shifters Replacement Considerations

The SY100S391JC is the tube-packaged equivalent. The SY100S391JCTR is the tin-lead tape and reel variant. Verify compatibility with the Fairchild F100K if substituting legacy designs.
