CD4089BE

Specialty Logic Overview

The CD4089BE is a binary rate multiplier integrated circuit manufactured by Harris Corporation, now part of Texas Instruments. It operates within a supply voltage range of 3V to 18V and utilizes a 16-lead dual-in-line package. The device functions as a 4-bit logic component designed to generate output pulses at frequencies that are programmable fractions of an input clock signal.

Specialty Logic Feature Summary

• Generates output pulses at programmable fractional frequencies relative to the input clock signal
• Operates with a wide supply voltage range from 3V to 18V
• Designed for through-hole mounting in standard 16-pin dual-in-line packages

Specialty Logic Applications

• Frequency division circuits
• Programmable pulse generation systems
• Digital clock signal processing

Specialty Logic Procurement Notes

Verify manufacturer attribution carefully, as the component was originally produced by Harris Corporation before acquisition by Texas Instruments. Confirm package type compatibility and ensure I/O voltage levels match connected logic ICs. Check for RoHS compliance status if required for specific manufacturing standards.

Specialty Logic Selection Notes

Select this component when a dedicated binary rate multiplier function is required for frequency scaling applications. Ensure the design accommodates the 3V to 18V operating range and verify that the 16-pin DIP footprint fits the target PCB layout constraints without requiring surface-mount alternatives.

Specialty Logic Part Context

This component belongs to the CD4089B series of specialty logic devices. Originally documented under Harris Semiconductor specifications, it represents a legacy CMOS logic family product. The BE suffix typically denotes the epoxy plastic dual-in-line package variant used in through-hole assembly processes.

Specialty Logic Replacement Considerations

Direct substitutes include other CD4089B variants from Texas Instruments or compatible binary rate multipliers from major logic manufacturers. Verify pinout compatibility and electrical characteristics before substitution.
