SY100EL57LZI

Signal Switches, Multiplexers, Decoders Overview

The SY100EL57LZI is a full differential 4:1 multiplexer from the 100EL series, manufactured by Microchip Technology. It operates on a 3.3V power supply and supports VEE ranging from -4.0V to -3.0V. The device features four differential data inputs (D0-D3), two select lines (SEL0, SEL1), and differential outputs (Q). It includes internal 75KΩ input pulldown resistors and provides dual VBB reference outputs for single-ended or AC coupled interfaces. Packaged in a 16-pin narrow SOIC (Z16-2) with an industrial temperature range of -40°C to +85°C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify component authenticity through authorized channels. Confirm RoHS compliance status and lead finish specifications (NiPdAu for Pb-Free variants). Ensure proper handling procedures are followed due to moisture sensitivity. Validate that the specific ordering suffix matches the required package type and operating temperature range before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a fully differential multiplexer is required for low skew signal routing. It is suitable for designs needing configurable 4:1 or 2:1 functionality within a 16-pin SOIC footprint. Consider the internal pulldown resistors for simplified 2:1 configuration. Verify compatibility with 3.3V logic levels and ECL/PECL voltage swings.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 100EL series of high-speed logic devices originally developed by Micrel, Inc., now under Microchip Technology. The series focuses on ECL-compatible components optimized for high-frequency applications. The ZG suffix indicates a Pb-Free package with NiPdAu lead finish, while ZI denotes the industrial temperature grade.

Signal Switches, Multiplexers, Decoders FAQ

How can the SY100EL57LZI be configured as a 2:1 multiplexer?

By leaving the SEL1 line open, it is pulled LOW via the internal 75KΩ pulldown resistors, allowing SEL0 to select between D0 and D1.

What is the function of the VBB outputs?

The VBB outputs provide a reference voltage for single-ended or AC coupled interfaces. They should be connected to the data bar inputs and bypassed via a 0.01µF capacitor to ground.
