SY100EL57ZG

Signal Switches, Multiplexers, Decoders Overview

The SY100EL57ZG is a fully differential 4:1 multiplexer from the ECL logic family, manufactured by Microchip Technology. It operates with 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 AC-coupled interfaces. Packaged in a 16-pin SOIC, it supports industrial temperature ranges (-40°C to +85°C) and includes internal input pulldown resistors.

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 by leaving the SEL1 line open
• Dual VBB reference outputs facilitate single-ended or AC coupled interface connections
• Integrated 75KΩ internal input pulldown resistors simplify circuit design
