MC100EL33DTR2

Counter Dividers Overview

The MC100EL33DTR2 is a divide-by-4 clock divider from the onsemi MC100EL series, designed for high-speed ECL applications. It operates with a maximum output frequency of 4.2 GHz and supports power supply voltages ranging from 4.2 V to 5.7 V. The device features an SOIC-8 surface-mount package and functions within a temperature range of -40°C to +85°C. It draws a typical operating current of 27 mA. This component serves as a clock driver and distribution element, providing precise frequency division for differential clock inputs in demanding digital systems.

Counter Dividers Feature Summary

• Provides divide-by-4 frequency division functionality for clock signals
• Supports high-speed operation up to 4.2 GHz toggle rate
• Features asynchronous reset capability for system synchronization
• Includes internal temperature compensation for stable performance across operating temperatures

Counter Dividers Applications

• High-speed clock distribution networks
• Frequency synthesis circuits
• Data communication systems requiring precise clock timing
• Test and measurement equipment

Counter Dividers Procurement Notes

Verify end-of-life status carefully, as the MC100EL33DG variant is listed as obsolete. Confirm availability through authorized distributors or secondary markets. Ensure the specific tape-and-reel packaging matches production requirements. Validate RoHS compliance details against current manufacturing data sheets before integration into new designs.

Counter Dividers Selection Notes

Select this component when a divide-by-4 ratio is required for 5V ECL logic families. Compare against the MC100EP33 series if 3.3V/5V dual-voltage compatibility is needed. Consider the MC100EL32 for divide-by-2 applications. Ensure the design accommodates the SOIC-8 footprint and thermal characteristics associated with the 27 mA operating current draw.

Counter Dividers Part Context

This part belongs to the MC100EL family of emitter-coupled logic devices, which are engineered for high-speed digital processing. The series includes dividers, flip-flops, and drivers. The '33' designation specifically indicates a divide-by-4 function. These components are integral to maintaining signal integrity in high-frequency environments where low jitter and fast propagation delays are critical.

Counter Dividers Replacement Considerations

The MC100EL33DG is a direct pin-compatible alternative but is marked as obsolete. The MC100EP33D offers similar divide-by-4 functionality with different voltage tolerances. Verify electrical specifications and package dimensions before substituting any cross-reference parts.
