100LVELT22M

Overview

The Fairchild Semiconductor 100LVELT22M is a unidirectional mixed-signal translator featuring two independent channels. It converts single-ended LVCMOS or LVTTL input signals into differential LVPECL outputs. The device operates on a 3.3V supply with a maximum voltage of 3.8V and a minimum of 3.0V. It exhibits a propagation delay of 0.6 ns. The component is housed in an 8-pin SOIC package and supports an operational temperature range from -40°C to 85°C.

Feature Summary

• Converts single-ended LVCMOS/LVTTL inputs to differential LVPECL outputs
• Contains two independent translation channels for enhanced routing flexibility
• Operates within a standard industrial temperature range

Applications

• Digital control systems requiring level shifting
• Signal routing interfaces between different logic families
• Level logic conversion in mixed-signal circuits

Procurement Notes

Verify the specific manufacturer designation, as Fairchild Semiconductor operations are now part of onsemi. Confirm that the 8-pin SOIC package matches the design requirements. Ensure the 3.3V operating voltage aligns with the target system power rails. Check the lead time availability, as production cycles may vary based on current manufacturing schedules and order volume constraints.

Selection Notes

Select this component when interfacing low-voltage CMOS or TTL logic with high-speed LVPECL receivers. The dual-channel architecture allows for parallel signal translation without additional external components. Verify that the 0.6 ns propagation delay meets the timing constraints of the application. Ensure the 8-pin SOIC footprint is compatible with the PCB layout and assembly processes.

Part Context

This device belongs to the 100LVELT22 series of translators designed for high-speed digital applications. It bridges the gap between lower voltage logic standards and the LVPECL standard commonly used in clock distribution and high-frequency data transmission. The unidirectional nature simplifies circuit design by defining a clear signal flow from input to output stages.

Replacement Considerations

The MC100LVELT22DR2G is a documented equivalent part number from onsemi. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement part meets the same thermal and voltage requirements.
