SY100E452JI

Flip Flops Overview

The SY100E452JI is a 5-bit differential register manufactured by Microchip Technology, housed in a 28-LCC (J-Lead) surface-mount package. It operates on a negative supply voltage ranging from -4.2 V to -5.5 V and supports a maximum clock frequency of 1.4 GHz with a propagation delay of 850 ps. The device features a single D-type element with positive edge triggering and an asynchronous master reset function. Designed for CMOS logic applications, it functions within a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Provides 5-bit data storage using differential signaling for D inputs, clocks, and outputs.
• Includes an asynchronous master reset function to initialize the register state independently of the clock signal.
• Supports extended voltage operation within the 100E series specifications for high-speed digital applications.

Flip Flops Applications

• High-speed serial data buffering in communication systems
• Differential clock distribution networks requiring precise timing alignment
• Digital signal processing interfaces utilizing ECL-compatible logic levels

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm RoHS compliance details via official documentation. Check moisture sensitivity handling requirements prior to assembly. Validate pinout compatibility with existing PCB layouts. Review datasheet revisions for any functional updates or design warnings.

Flip Flops Selection Notes

Select this component for designs requiring differential 5-bit latching with fast toggle frequencies. Ensure power supply rails match the specified negative voltage range. Consider thermal management for SMD packages in enclosed environments. Verify interface compatibility with source drivers supporting differential signals. Evaluate replacement options if long-term availability is critical.

Flip Flops Part Context

This part belongs to the SY10/100E452 family of differential registers produced by Microchip Technology. It succeeds earlier Micrel Inc. designs under the same functional designation. The J-Lead package variant offers surface-mount convenience compared to through-hole alternatives. It serves as a specialized logic IC for high-performance digital circuitry.

Flip Flops Replacement Considerations

SY100E452JY and SY100E452JC-TR are documented variants within the same product family offering identical electrical characteristics but differing in packaging formats such as tube or reel configurations.
