MC14014BFR2

Shift Registers Overview

The MC14014BFR2 is an 8-bit static shift register from the Motorola 4000B series, manufactured by onsemi. It utilizes CMOS technology with push-pull outputs and is housed in a 16-SOIC package. The device supports parallel-in serial-out data transfer modes. It operates within a supply voltage range of 3V to 18V and functions across an industrial temperature range of -55°C to +125°C.

Shift Registers Feature Summary

• CMOS construction using P-channel and N-channel enhancement mode MOS transistors for low power consumption
• Push-pull output configuration providing high noise immunity and direct interface capability
• Static operation ensuring data retention without requiring continuous clocking

Shift Registers Applications

• Parallel-to-serial data conversion in digital communication systems
• Serial-to-parallel data expansion for display drivers
• General-purpose bit shifting operations in microcontroller peripheral interfaces

Shift Registers Procurement Notes

Verify the manufacturer marking indicates onsemi or Motorola legacy branding. Confirm the suffix FR2 corresponds to the 16-SOIC tape and reel packaging format. Ensure the component meets RoHS compliance standards if required for the specific assembly process. Cross-reference the date code to confirm production lineage.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with parallel input capability is required. The wide supply voltage range allows compatibility with various logic families. The SOIC package facilitates surface-mount assembly. Consider the MC14021B as a functional alternative if pinout differences are acceptable.

Shift Registers Part Context

This part belongs to the 4000B series of CMOS logic devices originally developed by Motorola. The series is known for robust performance in harsh environments. The MC14014B variant specifically provides eight stages of shift storage with parallel load functionality, distinguishing it from standard serial-only shift registers.

Shift Registers Replacement Considerations

The MC14021B is a documented substitute offering identical 8-bit shift functionality. Verify that the pinout compatibility aligns with the existing PCB layout before substitution.
