MC100E142FN

Shift Registers Overview

The MC100E142FN is a 9-bit shift register from the onsemi 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 operates with a minimum shift frequency of 700 MHz and features dual clock inputs (CLK1, CLK2) and an asynchronous master reset. It accepts parallel data via D0-D8 and serial data via S-IN. The component utilizes 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 is housed in a PLCC-28 package.

Shift Registers Feature Summary

• Supports byte-parity applications with 9-bit capacity
• Features asynchronous master reset and dual clock inputs
• Includes internal input pulldown resistors to minimize noise

Shift Registers Applications

• Byte-parity generation and checking circuits
• Serial-to-parallel data conversion systems
• Parallel-to-serial data transmission interfaces

Shift Registers Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation, as availability may vary. Confirm that the procurement channel provides original manufacturer components to ensure authenticity. Check for RoHS compliance status if required by project specifications, noting that lead-free options exist within the product family. Ensure proper handling procedures are followed due to moisture sensitivity level requirements.

Shift Registers Selection Notes

Select this component when designing high-speed ECL logic circuits requiring byte-level data manipulation. The 100E series offers temperature compensation for stable performance across varying thermal conditions. Consider the PLCC-28 package constraints for PCB layout. Verify power supply configurations match either PECL or NECL operating ranges before integration into the system design.

Shift Registers Part Context

This part belongs to the MC10E/100E142 family of 5V/EnECL shift registers. The 100E series specifically includes temperature compensation features not present in the standard 10E series. It is manufactured by onsemi (formerly Semiconductor Components Industries, LLC) and is intended for high-performance digital signal processing applications requiring reliable data shifting capabilities.

Shift Registers Replacement Considerations

MC10E142FN serves as the non-temperature-compensated alternative within the same functional family.
