SY100S317DC

Overview

The SY100S317DC is a configurable logic gate manufactured by Micrel Inc., housed in a 24-pin CERDIP package. It integrates three independent circuits capable of functioning as AND or OR gates. The device supports twelve inputs distributed across the three circuits, with four inputs allocated to each circuit. Designed for high-performance ECL systems, it operates within an extended supply voltage range and features internal input pull-down resistors to ensure stable logic levels.

Feature Summary

• Configurable logic architecture allowing selection between AND and OR gate functions for each of the three internal circuits
• Integrated internal pull-down resistors on all inputs to maintain defined logic states
• Compatible with industry standard 100K ECL logic levels for seamless system integration

Applications

• High-performance ECL system logic implementation
• Digital signal processing configurations requiring configurable gate topology
• Complex logic function generation in telecommunications equipment

Procurement Notes

Verify the specific suffix DC against the manufacturer's current datasheet to confirm pinout compatibility and package integrity. Ensure the sourcing channel provides original Microchip or Micrel documentation. Confirm that the application environment matches the specified ECL voltage requirements. Check for any updated revision notes regarding internal resistor values or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a single package must provide multiple configurable logic gates in an ECL environment. It serves as a direct replacement for legacy 100K series devices where space efficiency and logic flexibility are required. Consider the 24-pin CERDIP form factor for through-hole mounting constraints. Evaluate power consumption relative to other ECL families if thermal management is critical.

Part Context

This part belongs to the Micrel 100K/100E ECL logic family, known for high-speed operation and noise immunity. Micrel was acquired by Microchip Technology, which continues to support these legacy high-speed logic products. The SY100S317DC represents a specialized configurable gate solution within this portfolio, distinct from multiplexers or shift registers found in the same series.

Replacement Considerations

Cross-reference with Motorola MC100S317 for functional equivalence. Verify pin-to-pin compatibility with Fairchild F100K series equivalents if migrating existing designs. Ensure substitute parts support the same 24-CERDIP package and ECL voltage specifications.
