MC10E141FNR2G

Shift Registers Overview

The MC10E141FNR2G is an 8-bit full-function shift register from the onsemi 10E series, designed for high-speed digital applications. It supports serial/parallel input and serial/parallel output with bi-directional shifting capabilities via DL/DR inputs. The device operates in PECL mode (VCC 4.2 V to 5.7 V, VEE = 0 V) or NECL mode (VCC = 0 V, VEE −4.2 V to −5.7 V). It features a minimum shift frequency of 700 MHz, asynchronous master reset, and internal 50 kΩ input pulldown resistors. Packaged in a 28-PLCC surface-mount format, it includes ESD protection exceeding 2 kV HBM.

Shift Registers Feature Summary

• Bi-directional shifting capability allowing data movement in either direction through dedicated left/right serial inputs.
• Full-function architecture supporting both parallel loading and serial shifting operations simultaneously.
• Integrated asynchronous master reset for immediate initialization of the shift register state.
• Internal input pulldown resistors ensure stable logic levels when inputs are floating or open.

Shift Registers Applications

• High-speed serial-to-parallel data conversion in communication systems
• Parallel-to-serial data serialization for transmission interfaces
• Digital signal processing pipelines requiring bi-directional data buffering
• Test equipment utilizing fast shift register chains for pattern generation

Shift Registers Procurement Notes

Verify component authenticity as this part may be discontinued or available only through secondary distributors. Confirm package integrity and moisture sensitivity handling requirements prior to assembly. Check for RoHS compliance status specific to the manufacturing batch, as older stock may differ from lead-free specifications. Ensure supply chain documentation matches the exact suffix FNR2G for reel packaging configuration.

Shift Registers Selection Notes

Select this component for designs requiring high-frequency shift registers with flexible input/output configurations. Consider the 28-PLCC package constraints for PCB layout and thermal management. Evaluate power supply stability for PECL or NECL operation modes. Compare against pin-compatible alternatives like the E241 if specific feature sets differ. Verify interface voltage compatibility with existing system logic levels before integration.

Shift Registers Part Context

The MC10E141 belongs to the 10E series of ECL logic devices, known for high-speed performance. It is functionally similar to the MC10E241 but offers enhanced bi-directional shifting features. The device is manufactured by onsemi and is part of their legacy high-speed logic portfolio. It is designed to meet JEDEC latchup standards and provides robust ESD protection for reliable operation in noisy environments.

Shift Registers Replacement Considerations

The MC10E241 is a pin-compatible alternative within the same series. Verify functional equivalence regarding shift direction control and reset mechanisms. Check datasheet revisions for any changes in electrical characteristics or package dimensions. Ensure substitute parts match the required operating voltage range and speed specifications.
