CD4541BPWR

Overview

The CD4541BPWR is a CMOS programmable timer integrated circuit manufactured by Texas Instruments. It features a single internal timer with a 14-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 sixteen-stage binary counter, providing selectable divide-by ratios via address inputs. The component is rated for an operating temperature range from -55°C to +125°C and includes auto-reset capabilities for continuous or single-cycle timing operations.

Feature Summary

• CMOS Programmable Timer with 16-stage binary counter
• Supply Voltage Range: 3V to 20V
• Operating Temperature: -55°C to +125°C
• Package: 14-TSSOP (0.173", 4.40mm width)

Applications

• Timing circuits requiring programmable delay intervals
• Frequency division applications using selectable counter stages
• Auto-reset oscillators for periodic signal generation

Procurement Notes

Verify the suffix 'PWR' corresponds to the 14-TSSOP package and tape-and-reel shipping format. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure pinout compatibility with the target PCB footprint design.

Selection Notes

Select this component when a surface-mount solution is required for programmable timing tasks. The TSSOP-14 package suits space-constrained designs. Verify that the 100kHz frequency limit meets system requirements. Consider the wide temperature range (-55°C to +125°C) for industrial environments.

Part Context

This part belongs to the CD4541B series of CMOS programmable timers. It shares core functionality with other variants like the DIP-14 CD4541BE and SOIC-14 CD4541BM, differing primarily in packaging and mounting style. The BPWR variant specifically denotes the thin-shrink small-outline package configuration.

Replacement Considerations

Direct pin-compatible alternatives include CD4541BE (PDIP) and CD4541BM (SOIC). Verify package dimensions and thermal characteristics when substituting through-hole or standard SOIC parts for surface-mount designs.
