MC100LVEL33DR2

Counter Dividers Overview

The MC100LVEL33DR2G is a 3.3 V ECL divide-by-4 counter manufactured by onsemi in an SOIC-8 package. It operates with a supply voltage range of 3.0 V to 3.8 V for PECL mode and -3.0 V to -3.8 V for NECL mode. The device features a typical propagation delay of 630 ps and supports a maximum toggle frequency of 4.0 GHz at 25°C. It includes an asynchronous reset pin, internal input pulldown resistors, and a dedicated VBB reference voltage output. The component meets JEDEC latchup specifications and offers ESD protection exceeding 4 kV (HBM) and 200 V (MM).

Counter Dividers Feature Summary

• Integrated divide-by-4 divider functionality with asynchronous reset capability.
• Supports both PECL and NECL operating modes within specified voltage ranges.
• Includes internally generated VBB reference voltage for single-ended inputs or AC coupling rebiasing.
• Features temperature compensation and internal input pulldown resistors.

Counter Dividers Applications

• High-speed clock distribution networks requiring frequency division.
• Synchronization of multiple LVEL33 devices in complex digital systems.
• AC coupled input signal processing using the VBB reference pin.

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'DR2G' corresponds to the SOIC-8 tape and reel packaging configuration. Confirm that the required moisture sensitivity level aligns with the SOIC-8 designation, which is Level 1. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range for guaranteed electrical performance.

Counter Dividers Selection Notes

Select this component when a 3.3 V ECL divide-by-4 function is required with high-frequency operation up to 4.0 GHz. Consider the SOIC-8 package if surface-mount assembly is preferred over TSSOP. Evaluate the need for the internal VBB pin if single-ended inputs or AC coupling are utilized in the design architecture.

Counter Dividers Part Context

This part belongs to the MC100LVEL series, which provides low-voltage ECL logic compatible with 3.3 V supplies. It is functionally equivalent to the legacy EL33 device but optimized for modern 3.3 V applications. The series maintains standard ECL timing characteristics while offering improved power efficiency and compatibility with contemporary system architectures.

Counter Dividers Replacement Considerations

The MC100LVEL33DG serves as a tube-packaged alternative within the same functional family. Verify pinout compatibility and electrical specifications before substituting different packaging options.

Counter Dividers FAQ

How should the VBB pin be handled if not used?

If the VBB pin is not utilized for single-ended inputs or AC coupling rebiasing, it must be left open-circuit.

What is the behavior of the flip-flops upon power-up?

Upon power-up, the internal flip-flops attain a random state; the asynchronous reset pin allows for synchronization of multiple devices in a system.
