SY100S336AFC

Specialty Logic Overview

The SY100S336AFC is a high-performance ECL component manufactured by Microchip Technology, functioning as a modulo-16 up/down counter or a 4-bit bidirectional shift register. It supports a maximum shift frequency of 700 MHz and features a clock-to-Q propagation delay with a maximum of 1100 ps. The device operates within an extended supply voltage range of VEE = –4.2V to –5.5V. It includes internal 75KΩ input pull-down resistors and industry standard 100K ECL levels. Available in a 24-pin CERPACK package (F24-1), it provides function and pinout compatibility with Fairchild F100K.

Specialty Logic Feature Summary

• Enhanced speed performance for cascaded multi-stage counters with significantly improved Sn to TC speed and reduced set-up/hold times compared to the base model.
• Voltage and temperature compensation mechanisms integrated to improve noise immunity across operating conditions.
• Flexible configuration options allowing operation as either a modulo-16 up/down counter or a 4-bit bidirectional shift register via Select inputs.

Specialty Logic Applications

• High-performance ECL systems requiring fast counting or shifting operations
• Cascaded multi-stage counter designs utilizing Count Enable controls
• Bidirectional data shifting applications using Serial Data inputs

Specialty Logic Procurement Notes

Verify that the specific ordering suffix matches the required package type and lead finish. Confirm the part number corresponds to the commercial operating temperature range and the 24-pin CERPACK format. Ensure compliance with RoHS requirements if applicable, noting that Pb-Free variants carry distinct markings. Cross-reference the manufacturer's latest datasheet for any updates on availability or recommended design practices.

Specialty Logic Selection Notes

Select this component when system timing requires a maximum shift frequency of 700 MHz and low propagation delays. Consider the enhanced Sn to TC speed improvements over the standard SY100S336 for complex cascading architectures. Evaluate the need for the 24-pin CERPACK footprint against available board space and thermal constraints. Verify that the power supply can accommodate the specified VEE range and current consumption characteristics.

Specialty Logic Part Context

This component belongs to the 100S series of ECL logic devices designed for high-speed digital applications. It serves as an evolution of the SY100S336, specifically optimized for higher clock frequencies in multi-stage configurations. The device maintains backward compatibility with legacy Fairchild F100K designs while offering superior electrical performance metrics.

Specialty Logic Replacement Considerations

The SY100S336A offers enhanced speed characteristics over the standard SY100S336. For direct functional and pinout compatibility, the Fairchild F100K is referenced as a compatible alternative.
