SY100EL57ZI

Signal Switches, Multiplexers, Decoders Overview

The SY100EL57ZI is a fully differential 4:1 multiplexer from the ECL logic family, manufactured by Microchip Technology. It operates on a single -5V power supply and features four differential data inputs (D0-D3) and two select lines (SEL0, SEL1). The device provides differential outputs (Q, Q-bar) and dual VBB reference outputs for single-ended or AC-coupled interfaces. It includes 75KΩ internal input pulldown resistors and is housed in a 16-pin SOIC package with an industrial temperature range of -40°C to +85°C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Fully differential architecture designed for low skew applications such as clock distribution
• Configurable as either a 4:1 or 2:1 multiplexer via the state of the SEL1 line
• Dual VBB reference outputs facilitate single-ended or AC-coupled interface connections

Signal Switches, Multiplexers, Decoders Applications

• Low skew clock distribution systems
• High-speed signal routing in ECL logic circuits
• AC-coupled differential data switching

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify component authenticity through authorized channels due to the NRND status. Confirm that the specific ordering suffix matches the required lead finish and packaging format. Ensure procurement specifications align with the industrial temperature rating and absolute maximum ratings defined in the official datasheet.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a fully differential multiplexer is required for high-speed ECL applications. It is suitable for designs needing configurable 4:1 or 2:1 mux functionality within an industrial temperature environment. Verify compatibility with -5V power supplies and ensure PCB layout supports differential signaling requirements.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SY10/100EL57 series of differential multiplexers originally developed by Micrel, Inc., now under Microchip Technology. The '100' designation indicates operation at standard ECL voltage levels (-5V), while the 'ZI' suffix specifies the industrial temperature range and SOIC-16 package configuration.
