CD4089BNSR

Specialty Logic Overview

The CD4089BNSR is a CMOS binary rate multiplier manufactured by Texas Instruments, housed in a 16-pin SOIC surface-mount 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 independent 4-bit channels with dedicated inputs for data, clock, and enable control. Key electrical specifications include a low-level output current of 6.8 mA and a high-level output current of -6.8 mA at 15 V. Propagation delay is typically 75 ns at 15 V with a 50 pF load.

Specialty Logic Feature Summary

• Performs binary multiplication by combining two 4-bit binary numbers to produce an 8-bit weighted output.
• Includes individual channel enable inputs to selectively activate specific multipliers without affecting others.
• Provides synchronous operation controlled by a single clock input per channel.

Specialty Logic Applications

• Frequency synthesis circuits requiring variable division ratios
• Digital signal processing systems needing real-time scaling
• Programmable timing generators

Specialty Logic Procurement Notes

Verify the suffix 'NSR' confirms the SOIC-16 package and reel packaging format. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the operating environment remains within the specified -55 °C to +125 °C temperature range to maintain performance guarantees.

Specialty Logic Selection Notes

Select this component when a CMOS-compatible binary multiplier is required for high-voltage applications up to 18 V. The SOIC-16 package suits automated surface-mount assembly processes. Consider the propagation delay characteristics relative to system clock speeds to ensure timing integrity.

Specialty Logic Part Context

This part belongs to the CD4000B series of high-voltage CMOS logic devices. It serves as a functional alternative to other binary multipliers like the CD4089BE or CD4089BMS, offering equivalent logical functionality in a surface-mount form factor suitable for modern PCB layouts.

Specialty Logic Replacement Considerations

CD4089BE (DIP-16), CD4089BMS (SOIC-16). Verify pinout compatibility before substitution.
