SY100EL57ZC

Signal Switches, Multiplexers, Decoders Overview

The SY100EL57ZC 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 data outputs (Q) and dual VBB reference outputs for single-ended or AC-coupled interfaces. It is housed in a 16-pin SOIC package with an operating temperature range of -40°C to +85°C.

Signal Switches, Multiplexers, Decoders FAQ

How does the device function as a 2:1 multiplexer?

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

What is the purpose of the VBB outputs?

The VBB outputs provide a reference voltage for single-ended or AC-coupled interfaces and can source/sink up to 0.5mA of current.
