CD4089BPWR

Specialty Logic Overview

The CD4089BPWR is a CMOS binary rate multiplier manufactured by Texas Instruments, belonging to the 4000B series. It operates within a supply voltage range of 3 V to 18 V and supports a maximum clock frequency of 25 MHz at 10 V. The device features four selectable binary weights (1, 2, 4, and 8) controlled by input pins A through D. It includes an enable input for controlling data flow and provides both true and complement outputs. Packaged in a 16-TSSOP surface-mount case, it functions reliably across an industrial temperature range of -55°C to +125°C.

Specialty Logic Feature Summary

• Provides four independently selectable binary weighting factors (1, 2, 4, and 8) via dedicated address inputs.
• Features a dedicated enable input that controls the passage of clock pulses to the output stages.
• Delivers simultaneous true and complement logic outputs for flexible circuit integration.

Specialty Logic Applications

• Frequency division circuits requiring variable division ratios
• Digital synthesizers generating specific harmonic frequencies
• Pulse width modulation systems utilizing binary weighted timing

Specialty Logic Procurement Notes

Verify the exact suffix against current manufacturer documentation to confirm package type and environmental compliance. Confirm availability status as distribution channels may vary. Ensure the operating environment remains within the specified voltage and temperature limits defined in the official datasheet.

Specialty Logic Selection Notes

Select this component when a fixed binary multiplication ratio is required rather than arbitrary counting. Compare propagation delay specifications against system timing requirements. Verify that the TSSOP-16 footprint aligns with the target PCB layout constraints.

Specialty Logic Part Context

This part belongs to the CD4000B family of high-voltage CMOS logic devices produced by Texas Instruments. These components are designed for general-purpose digital applications requiring low power consumption and wide operating voltage ranges. The CD4089 specifically addresses binary rate multiplication needs within this standard logic portfolio.

Specialty Logic Replacement Considerations
