MC100E195FN

Overview

The MC100E195FN is a programmable delay line integrated circuit manufactured by onsemi. It features a single independent delay circuit with 128 taps, providing a total adjustable delay range from 1.39 ns to 3.63 ns. The tap increment is specified at 20 ps. The device operates within a supply voltage range of 4.2 V to 5.7 V and supports surface mount installation in a 28-LCC (J-Lead) package. It is rated for an operating temperature range of 0°C to 85°C.

Feature Summary

• Programmable delay functionality with 128 selectable taps
• Differential output configuration suitable for high-speed timing applications
• Surface-mount construction in a 28-lead LCC package

Applications

• High-speed clock distribution networks requiring precise phase alignment
• Data acquisition systems needing controlled signal path delays
• Test and measurement equipment utilizing programmable timing elements

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance requirements as the datasheet indicates non-compliance. Validate moisture sensitivity level (MSL 3) handling procedures during assembly. Ensure supply chain sources provide original manufacturer documentation to confirm part revision and manufacturing origin.

Selection Notes

Select this component when a fixed delay line is insufficient and programmability is required. Compare against the MC100EP195 series if lower voltage operation or different packaging is needed. Verify that the 28-LCC footprint matches the target PCB layout. Consider the 20 ps resolution for fine-timing adjustments in differential signaling environments.

Part Context

This part belongs to the MC100E family of ECL-compatible timing components. It serves as a specialized element for managing signal propagation times in high-frequency digital circuits. The device complements other logic families by offering precise, user-adjustable latency without external discrete components.

Replacement Considerations

Direct substitutes include the MC100E195FNR2 and MC100E195FNR2G. These variants maintain identical functional specifications but differ in tape-and-reel packaging instead of tubes. Verify pinout compatibility before integration into existing designs.
