CD4089BF3A

Specialty Logic Overview

The CD4089BF3A is a CMOS binary rate multiplier manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and supports input frequencies up to 3.5 MHz. The device functions as a single-circuit logic component in the 4000 series, designed for digital clock generation and frequency multiplication applications. It is housed in a 16-pin TSSOP package and is rated for operation across an extended temperature range from -55°C to +125°C.

Specialty Logic Feature Summary

• CMOS binary rate multiplier functionality
• Wide operating voltage capability
• Extended industrial temperature rating

Specialty Logic Applications

• Digital clock generation
• Frequency multiplication circuits
• Binary rate scaling systems

Specialty Logic Procurement Notes

Verify the specific suffix BF3A against the official Texas Instruments CD4089B Types datasheet to confirm pinout compatibility and packaging details. Ensure the source document explicitly lists this part number as active or recommended for new designs, as some variants may be marked NRND. Cross-reference the TSSOP-16 package dimensions with your PCB footprint requirements before finalizing procurement.

Specialty Logic Selection Notes

Select this component when a CMOS binary rate multiplier is required for high-voltage applications up to 18 V. The wide temperature range makes it suitable for harsh environments. Compare performance against the standard CD4089B if lead-free processing or specific tape-and-reel packaging (indicated by the F3A suffix) is mandatory for automated assembly lines.

Specialty Logic Part Context

This component belongs to the Texas Instruments CD4089B family of high-voltage CMOS logic devices. It serves as a specialized binary rate multiplier within the broader 4000 series logic lineup. The device is functionally similar to other binary multipliers but offers specific voltage and temperature ratings defined by the B-type designation.

Specialty Logic Replacement Considerations

The CD4089BE is a documented alternative within the same family. Verify pin compatibility and electrical specifications against the official datasheet before substitution.
