MC100EL91DWR2

Translators, Level Shifters Overview

The MC100EL91DWR2 is a triple PECL to ECL translator manufactured by onsemi. It converts Low Voltage Positive Emitter Coupled Logic (LVPECL) or Positive Emitter Coupled Logic (PECL) inputs into complementary Emitter Coupled Logic (ECL) outputs. The device operates with VCC connected to a positive supply and VEE connected to a negative supply, typically ranging from -3.0V to -5.5V. It features temperature compensation for stable performance across varying thermal conditions. The component is housed in a 20-pin SOIC package.

Translators, Level Shifters Feature Summary

• Performs voltage level translation from LVPECL/PECL inputs to ECL outputs
• Includes temperature compensation for consistent operation across environmental changes
• Provides defined low output states when differential inputs are open or grounded

Translators, Level Shifters Applications

• High-speed digital signal processing systems requiring logic level conversion
• Clock management designs utilizing low skew and low jitter devices
