Device Structure

28-pin plastic leaded chip carrier (PLCC), J-lead mounting for surface mount (SMT) assembly. One integrated multiplexing circuit supporting five independent selection lines. Compact form factor allows direct soldering on standard PCBs.

Performance Characteristics

High-speed signal switching for multiple digital channels. Stable operation over a wide negative voltage range. Robust packaging ensures good mechanical stability during soldering and operation. Reliable for continuous operation in standard commercial environments.

Application Environments

Ideal for telecommunications infrastructure, networking hardware, high-speed digital logic systems, and signal routing applications. Commonly used in advanced computing systems and industrial control modules that require fast and precise multiplexing.

Selection Guidelines

Check supply voltage compatibility (-4.2V to -5.5V) with existing board design. Confirm required multiplexing configuration (5 channels, 2 inputs per channel). Evaluate packaging and mounting needs for PLCC versus alternative formats. Validate operating temperature requirements within 0°C to 85°C range. Ensure RoHS non-compliance does not conflict with project or regulatory demands.

Usage Considerations

This part requires negative voltage power supply. RoHS non-compliance may restrict use in projects requiring lead-free or green electronics. Confirm with board manufacturer and downstream users about material compliance. Discontinued status means limited future supply — ensure sufficiency for production and legacy support. Handle with standard moisture protection procedures per MSL 1 guidelines.

Potential Equivalent/Replacement Models

No direct RoHS-compliant alternatives from Microchip known for the SY100E154JC in 5x2:1 PLCC multiplexers. For similar multiplexing functions, consider looking at ON Semiconductor, Texas Instruments, or IDT high-speed multiplexer ICs, but verify voltage and pin compatibility.
