CD4541BPW

Overview

The CD4541BPW is a CMOS programmable timer and oscillator manufactured by Texas Instruments. It features a single internal timer circuit housed in a 14-pin TSSOP surface-mount package. The device operates within a supply voltage range of 3V to 20V and supports a maximum frequency of 100kHz. It functions as a monostable multivibrator or astable oscillator, utilizing external resistors and capacitors for timing control. The component is rated for an operating temperature range from -55°C to +125°C, ensuring reliability in industrial environments.

Feature Summary

• CMOS technology with low power consumption
• Programmable timing via external RC components
• Wide supply voltage range (3V to 20V)
• Available in 14-TSSOP surface-mount package

Applications

• Timing delay circuits
• Pulse width modulation generation
• Frequency division applications
• Watchdog timers

Procurement Notes

Verify the specific suffix 'PW' corresponds to the 14-TSSOP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity.

Selection Notes

Select this component for designs requiring precise timing intervals controlled by external passive components. Compare propagation delay specifications against system clock requirements. Verify that the TSSOP footprint matches the PCB layout constraints. Consider thermal dissipation limits if operating at maximum voltage and temperature extremes.

Part Context

This part belongs to the CD4541B series of programmable timers. It shares functional compatibility with other variants in the family, such as DIP or SOIC packages, while differing primarily in physical form factor and mounting style. The BPW designation specifically identifies the TSSOP version within the Texas Instruments product line.

Replacement Considerations

Direct pin-compatible alternatives include the CD4541BE (PDIP) and CD4541BM (SOIC). Verify package dimensions and thermal characteristics before substitution. Cross-reference datasheets to ensure identical electrical parameters and timing capabilities.
