MC10H141FNG

Shift Registers Overview

The MC10H141FNG is a four-bit universal shift register from the MECL 10H series, manufactured by onsemi. It operates with a single −8 V power supply and features a PLLC-20 package. The device supports serial/parallel to parallel data transfer modes controlled by select inputs S1 and S2. Key electrical parameters include a propagation delay of 1.0 to 2.1 ns, a minimum shift frequency of 250 MHz, and a typical power dissipation of 425 mW. It provides voltage compensated operation and improved noise margins over standard MECL 10K parts.

Shift Registers Feature Summary

• Performs shift left, shift right, parallel entry, and stop shift operations without external gating.
• Offers functional and pinout compatibility with standard MECL 10K parts while improving propagation delay and operating frequency.
• Features voltage compensated design for stable performance across operating voltage and temperature ranges.

Shift Registers Applications

• High-speed digital signal processing requiring universal shift capabilities.
• Data serialization and deserialization in communication systems.
• Parallel-to-serial conversion circuits in high-frequency logic applications.

Shift Registers Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status as indicated in current documentation. Check for specific ordering suffixes that may affect packaging or shipping quantities. Ensure procurement sources provide valid traceability records for quality assurance purposes.

Shift Registers Selection Notes

Select this component when MECL 10K compatibility is required alongside enhanced speed performance. Consider the PLLC-20 surface mount package for board space constraints. Evaluate thermal management requirements due to the specified power dissipation levels. Ensure system clock frequencies align with the minimum 250 MHz shift rate specification.

Shift Registers Part Context

This device belongs to the MC10H141 family within the MECL 10H logic series. It serves as an evolution of the legacy MECL 10K architecture, maintaining pin compatibility while delivering superior switching speeds. The part is designed for applications demanding reliable high-frequency data shifting in ECL-based systems.

Shift Registers Replacement Considerations

Direct replacements include other MC10H141 variants such as MC10H141P or MC10H141FNR2G, which share identical functionality but differ in package type or reel specifications. Verify lead-free status and package dimensions when substituting.
