CD4089BNS

Specialty Logic Overview

The CD4089BNS is a CMOS binary rate multiplier from the Texas Instruments 4000 series, housed in a 16-pin SOIC package. It operates within a supply voltage range of 3 V to 18 V and supports an extended temperature range from -55 °C to +125 °C. The device features four addressable bit inputs (A through D) with corresponding enable inputs, allowing for programmable frequency multiplication ratios. It includes dedicated carry-in and carry-out pins to facilitate cascading multiple units for higher-order multiplication functions without external logic.

Specialty Logic Feature Summary

• Configurable binary multiplication ratios via four independent addressable bit inputs
• Integrated carry propagation terminals for seamless multi-stage expansion
• High-voltage tolerant CMOS construction suitable for diverse power environments

Specialty Logic Applications

• Programmable frequency synthesizers
• Digital clock dividers and multipliers
• Pulse width modulation circuits
• Timing control systems requiring variable division ratios

Specialty Logic Procurement Notes

Verify the specific suffix 'NS' against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure the component meets the required operating temperature and voltage ratings for your specific application environment before finalizing procurement.

Specialty Logic Selection Notes

Select this component when a fixed-ratio divider is insufficient and a programmable multiplication factor is required. Compare it against standard counters if complex sequencing is needed, or against simpler gates if only basic logic operations are necessary. Consider the pin count and package availability relative to your board layout constraints.

Specialty Logic Part Context

This part belongs to the CD4000B series of high-voltage CMOS logic devices. It serves as a specialized arithmetic function block distinct from standard logic gates or memory elements. Its primary role in the portfolio is providing flexible digital signal processing capabilities for frequency manipulation tasks.

Specialty Logic Replacement Considerations

Check for equivalents such as CD4089BE or CD4089BM from Texas Instruments, ensuring the package style matches your assembly requirements. Other manufacturers may offer compatible parts like HCC4089B, but verify pin compatibility and electrical characteristics carefully.
