MC10E142FNR2G

Shift Registers Overview

The MC10E142FNR2G is a 9-bit shift register from the MC10E/100E series, designed for byte-parity applications. It supports serial/parallel in and serial/parallel out shifting in one direction (bit 0 to bit 8). The device features dual clocks (CLK1, CLK2) and accepts parallel data via inputs D0-D8 or serial data via S-IN. It operates in PECL mode with VCC = 4.2 V to 5.7 V (VEE = 0 V) or NECL mode with VEE = -4.2 V to -5.7 V (VCC = 0 V). The minimum shift frequency is 700 MHz. It includes an asynchronous master reset (MR) and internal input pulldown resistors.

Shift Registers Feature Summary

• Supports byte-parity applications with 9-bit capacity
• Features dual clock inputs for flexible timing control
• Includes asynchronous master reset function
• Operates in both PECL and NECL voltage modes

Shift Registers Applications

• Byte-parity generation and checking circuits
• High-speed serial-to-parallel data conversion
• Parallel-to-serial data transmission systems
• ECL-based digital signal processing chains

Shift Registers Procurement Notes

Verify the specific ordering suffix required for your application. The 'G' suffix indicates a lead-free package compliant with RoHS standards. Confirm moisture sensitivity level requirements, as Pb-Free versions have MSL 3 while standard Pb versions have MSL 1. Ensure the PLCC-28 package form factor matches your PCB footprint constraints before finalizing procurement.

Shift Registers Selection Notes

Select this component when designing ECL logic systems requiring 9-bit shift functionality with byte alignment. Choose the MC10E variant for standard operation or the MC100E variant if temperature compensation is needed for wider thermal stability. Ensure power supply rails match the selected PECL or NECL configuration. Verify that the PLCC-28 package is suitable for your assembly process and that termination networks are planned for unused outputs to minimize noise.

Shift Registers Part Context

This part belongs to the MC10E/100E family of 5V/EnECL logic devices manufactured by onsemi. These components are engineered for high-speed digital applications where low propagation delay and high toggle frequencies are critical. The family includes various registers, counters, and gates optimized for ECLinPS compatibility and robust performance in demanding communication and computing environments.

Shift Registers Replacement Considerations

The MC100E142FN serves as a functional equivalent within the same family, offering temperature compensation. Both share identical pinouts and logical functions. Verify that the replacement part meets the specific environmental and electrical requirements of the original design, particularly regarding operating temperature ranges and power supply tolerances.
