MC10E142FNR2

Shift Registers Overview

The MC10E142FNR2 is a 9-bit shift register from the ECLinPS family, 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 clock inputs (CLK1, CLK2) and accepts parallel data via D0-D8 or serial data via S-IN. Mode selection between SHIFT and LOAD is controlled by the SEL pin. An asynchronous Master Reset (MR) resets all registers to zero. It operates in PECL mode with VCC = 4.2 V to 5.7 V (VEE = 0 V) or NECL mode with VCC = 0 V (VEE = -4.2 V to -5.7 V). Maximum toggle frequency is 900 MHz at 25°C.

Shift Registers Feature Summary

• Supports byte-parity applications with 9-bit shifting capability
• 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 pipelines

Shift Registers Procurement Notes

Verify the specific ordering suffix 'R2' corresponds to tape and reel packaging containing 500 units per reel. Confirm RoHS compliance status if lead-free requirements are mandatory, as non-compliant versions exist. Ensure the PLCC-28 package dimensions match the target PCB footprint. Check current availability status as this component may be subject to discontinuation or lifecycle changes.

Shift Registers Selection Notes

Select this component when designing high-speed logic requiring ECL compatibility and byte-oriented data handling. The dual-clock architecture allows for complex timing schemes. Consider the internal input pulldown resistors for open-input protection. Verify that the power supply configuration matches either PECL or NECL standards. Evaluate thermal performance within the specified operating temperature range of 0°C to +85°C.

Shift Registers Part Context

This part belongs to the MC10E/100E142 series of 5V/EnECL 9-bit shift registers manufactured by onsemi. The '10E' designation indicates the standard series without temperature compensation, distinguishing it from the '100E' variant which includes temperature compensation features. The device utilizes a PLCC-28 plastic package.

Shift Registers Replacement Considerations

MC100E142FNR2G: Offers identical functionality but includes temperature compensation and Pb-Free packaging.
