MC100EP142MNR4G

Shift Registers Overview

The MC100EP142MNR4G is a 9-bit shift register from the onsemi MC100EP series, designed for byte-parity applications. It supports serial/parallel input and serial/parallel output with shifting in one direction (Bit 0 to Bit 8). The device operates in PECL mode (VCC = 3.0 V to 5.5 V, VEE = 0 V) or NECL mode (VCC = 0 V, VEE = −3.0 V to −5.5 V). It features dual clocks (CLK0, CLK1), an asynchronous master reset, and a typical shift frequency exceeding 2.8 GHz. The component is housed in a QFN-32 package.

Shift Registers Feature Summary

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

Shift Registers Applications

• Byte-parity generation and checking circuits
• High-speed serial data processing systems
• ECL-based digital logic designs requiring parallel-to-serial conversion

Shift Registers Procurement Notes

Verify the specific suffix MNR4G corresponds to the tape and reel packaging format containing 1000 units per reel. Confirm that the 100 Series designation indicates the inclusion of temperature compensation features compared to the standard 10 Series. Ensure compatibility with the required PECL or NECL power supply configurations during procurement planning.

Shift Registers Selection Notes

Select this component when designing systems requiring a 9-bit shift register with byte-parity capabilities. Choose the MC100EP142 over the MC10EP142 if temperature compensation is required for the application environment. Ensure the design supports the necessary dual-clock architecture and differential signaling requirements inherent to ECL logic families.

Shift Registers Part Context

This part belongs to the MC100EP family of high-speed ECL logic devices manufactured by onsemi. The family includes various shift registers and counters optimized for high-frequency operation. The MC100EP142 specifically addresses applications needing byte-aligned data handling within high-speed serial communication or processing architectures.

Shift Registers Replacement Considerations

MC10EP142MNR4G serves as a non-temperature-compensated alternative within the same package and pinout configuration.
