SY100S301JC

Overview

The SY100S301JC is a high-speed logic integrated circuit manufactured by Microchip Technology, belonging to the 100S series. It functions as a triple 5-input OR/NOR gate utilizing ECL (Emitter-Coupled Logic) technology. The device is housed in a 28-pin PLCC (Plastic Leaded Chip Carrier) package, specifically identified as PQCC28. This component provides three independent logic gates within a single chip, designed for applications requiring fast switching speeds and low propagation delay typical of ECL families.

Feature Summary

• Contains three independent 5-input logic gates capable of performing OR or NOR operations
• Utilizes ECL technology for high-speed signal processing
• Available in a 28-lead Plastic Leaded Chip Carrier (PLCC) surface-mount package

Applications

• High-speed digital logic circuits
• ECL-based system design
• Complex gate implementation in telecommunications equipment

Procurement Notes

Verify the specific manufacturer source, as listings may attribute this part to Synergy Semiconductor Corp or Micrel, which are now part of Microchip. Confirm the package type is strictly 28-PLCC and that the logic function matches the triple 5-input OR/NOR specification. Ensure compatibility with ECL power supply requirements before integration into designs.

Selection Notes

Select this component when a design requires multiple 5-input logic functions in a compact form factor. The ECL family offers superior speed compared to standard TTL or CMOS alternatives. Consider the 28-PLCC package constraints regarding PCB layout and thermal management. Verify that the system operates within the voltage and temperature ranges specified for the 100S series.

Part Context

This part belongs to the Microchip 100S series of high-speed ECL logic devices. The series includes various gates, buffers, and drivers optimized for performance-critical applications. The SY100S301JC specifically addresses needs for complex combinational logic with high fan-in capabilities in a standardized package format common in legacy and specialized high-speed systems.

Replacement Considerations

Check for direct equivalents such as SY100S301JCTR or SY100S301JC-TR from Microchip or former Synergy Semiconductor/Micrel sources. Ensure pinout and electrical characteristics match exactly when substituting.
