CD4046BPW

Overview

The CD4046BPWR is a CMOS micropower phase-locked loop (PLL) integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 18V and supports a maximum frequency of 2.4MHz. The device is housed in a 16-TSSOP package with dimensions of 4.40mm width. It functions as a single-channel PLL suitable for applications requiring low power consumption. The operational temperature range extends from -55°C to 125°C, ensuring reliability across industrial environments.

Feature Summary

• Integrates a complete phase-locked loop system on a single CMOS chip
• Features micropower consumption characteristics for energy-efficient operation
• Supports wide supply voltage ranges from 3V to 18V

Applications

• Frequency synthesis circuits
• FM demodulation systems
• Motor speed control loops

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and environmental compliance. Ensure the ordering code matches the required TSSOP-16 configuration. Cross-reference datasheet revisions to validate current manufacturing status and pinout compatibility before integration into design specifications.

Selection Notes

Select this component when a monolithic PLL solution with low power requirements is necessary. Confirm that the 2.4MHz maximum frequency meets system bandwidth needs. Verify that the 16-TSSOP package fits the available PCB footprint constraints. Check operating temperature limits against the intended application environment.

Part Context

This part belongs to the CD4046B family of phase-locked loops. It shares functional similarities with other variants like the CD4046BNSR but differs in packaging. The 'PWR' suffix specifically denotes the thin shrink small-outline package variant produced by Texas Instruments.

Replacement Considerations

The CD4046BPWRE4 is an equivalent lead-free version of this component. Other manufacturers offer compatible parts such as the HEF4046B or HCF4046B, though pinouts and electrical characteristics should be verified against original specifications.
