MC10E142FNG

Shift Registers Overview

The MC10E142FNG is a 9-bit shift register from the onsemi 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. Mode selection between SHIFT and LOAD is controlled by the SEL pin. An asynchronous Master Reset (MR) clears all registers. 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 package is PLCC-28.

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 and ESD protection

Shift Registers Applications

• Byte-parity generation and checking circuits
• High-speed serial-to-parallel data conversion
• PECL/NECL logic systems requiring shift register functionality

Shift Registers Procurement Notes

Verify the specific suffix 'G' indicates a lead-free package compliant with RoHS standards. Confirm the PLCC-28 footprint matches the design layout. Check moisture sensitivity level requirements for Pb-free components during assembly. Ensure power supply decoupling meets ECL termination guidelines specified in application notes.

Shift Registers Selection Notes

Select this component when a 9-bit shift register is required for parity applications within ECLinPS families. Choose the MC10E variant for standard operation or MC100E for temperature compensation if available in the same package. Verify voltage compatibility with either PECL or NECL power rails before integration into the system design.

Shift Registers Part Context

This part belongs to the MC10E/100E142 family of 5V/EnECL 9-bit shift registers. It shares functional similarities with other devices in the MC10E series but is distinct in its 9-bit width tailored for byte-parity tasks. The FNG suffix denotes a lead-free version in a PLCC-28 package, differentiating it from standard tin-lead variants.

Shift Registers Replacement Considerations

MC10E142FN is the non-lead-free equivalent. MC100E142FNG offers temperature compensation. MC10E141FNG is an 8-bit alternative.
