SY100S321JZ-TR

Inverter Gates Overview

The SY100S321JZ-TR is a monolithic 9-bit inverter from the 100S series, manufactured by Microchip Technology. It features nine single-input/single-output inverting buffer gates housed in a 28-pin PLCC package. The device operates within an extended supply voltage range of VEE = –4.2V to –5.5V. Key electrical specifications include a maximum propagation delay (tPLH/tPHL) of 700ps and a transition time (tTLH/tTHL) of 900ps at VEE = –5.5V. Power supply current (IEE) ranges from –55mA minimum to –25mA maximum with inputs open.

Inverter Gates Feature Summary

• Contains nine independent inverting buffer gates with single input and output for signal inversion.
• Features internal 75kΩ input pull-down resistors to improve noise immunity and stability.
• Includes voltage and temperature compensation mechanisms to enhance operational reliability.
• Functionally and pinout compatible with Fairchild F100K equivalents.

Inverter Gates Applications

• High-speed digital signal inversion in ECL logic circuits
• Data bus buffering and line driving applications
• System designs requiring compatibility with legacy Fairchild 300K/F100K architectures

Inverter Gates Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the Tape and Reel packaging variant as specified in the manufacturer's ordering information. Confirm the lead finish matches project requirements, distinguishing between Sn-Pb and Matte-Sn Pb-Free options. Ensure the component meets RoHS directives if applicable to the target assembly process. Cross-reference the specific date code and lot traceability against quality standards.

Inverter Gates Selection Notes

Select this component when a high-density 9-bit inverter solution is required within a compact 28-pin PLCC footprint. It is suitable for designs needing extended supply voltage flexibility down to –4.2V. Consider its compatibility with existing Fairchild-based schematics if migrating or maintaining legacy systems. Evaluate the 700ps propagation delay against system timing constraints to ensure adequate performance margins.

Inverter Gates Part Context

This part belongs to the 100S series of low-power ECL logic devices produced by Micrel, now part of Microchip Technology. The series focuses on providing high-speed performance with reduced power consumption compared to older technologies like Fairchild 300K. The SY100S321 specifically addresses the need for multiple inversion stages in a single integrated circuit package.

Inverter Gates Replacement Considerations

The datasheet explicitly states functional and pinout compatibility with the Fairchild F100K. Designers replacing legacy components should verify that the F100K meets all electrical parameters, particularly the extended voltage range and propagation delays, before substitution.
