MC100LVEL91DWR2

Translators, Level Shifters Overview

The MC100LVEL91DWR2 is a triple LVPECL to ECL translator manufactured by onsemi. It converts low voltage positive emitter coupled logic (LVPECL) or PECL input signals into differential ECL outputs compatible with -3.3V to -5.0V supplies. The device operates with three power rails: VCC connected to a positive supply, VEE to a negative supply, and GND to system ground. Both VCC and VEE require 0.01μF bypass capacitors to ground for stability. It features temperature compensation and ensures Q outputs default to low when inputs are open or grounded.

Translators, Level Shifters Feature Summary

• Converts LVPECL/PECL inputs to differential ECL outputs
• Includes temperature compensation for stable operation across varying thermal conditions
• Provides fail-safe output states when inputs are left open or grounded

Translators, Level Shifters Applications

• High-speed digital circuit signal translation
• Clock management systems requiring level shifting
• Voltage level interfacing between 3.3V and -3.3V/-5.0V domains

Translators, Level Shifters Procurement Notes

Verify the specific suffix DWR2 corresponds to the SOIC-20 package variant. Confirm RoHS compliance and halogen-free status as per manufacturer documentation. Ensure power supply requirements match the design's VCC and VEE specifications before integration.

Translators, Level Shifters Selection Notes

Select this component when interfacing 3.3V LVPECL sources with legacy -3.3V or -5.0V ECL loads. It is suitable for designs requiring complementary outputs and robust performance in high-speed environments where signal integrity and temperature stability are critical.
