SY100EL56VZI

Signal Switches, Multiplexers, Decoders Overview

The SY100EL56VZI is a dual, fully differential 2:1 multiplexer from the Microchip Technology ECL family. It supports 3.3V and 5V power supply options with a typical propagation delay of 440 ps. The device features separate and common select inputs, high bandwidth output transitions, and internal 75 kΩ input pull-down resistors for stability under open input conditions. It is available in a 20-lead SOIC package.

Signal Switches, Multiplexers, Decoders FAQ

How does the device behave when differential inputs are left open?

When both differential inputs are left open, the D input pulls down to VEE, the /D input biases around VCC/2, and the Q output is forced LOW.

What is the purpose of the multiple VBB pins on this device?

Multiple VBB pins are provided to ease the AC coupling of input signals.
