CD4541BPWRG4

Overview

The CD4541BPWRG4 is a CMOS programmable timer integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 20 V and supports a maximum frequency of 100 kHz. The device features a 65,536 counter and is housed in a 14-TSSOP surface-mount package. It functions as a single timer with CMOS output types. The component is rated for an operating temperature range from -55 °C to +125 °C, ensuring reliability across industrial conditions.

Feature Summary

• CMOS Programmable Timer IC with 65,536 count capability
• Supply Voltage Range: 3 V to 20 V
• Maximum Frequency: 100 kHz
• Operating Temperature: -55 °C to +125 °C
• Package: 14-TSSOP (0.173", 4.40mm width)

Applications

• Timing circuits requiring programmable delays
• Frequency division applications

Procurement Notes

Verify the G4 suffix indicates lead-free compliance and specific manufacturing lot details against the official datasheet. Confirm the 14-TSSOP package dimensions match the design footprint requirements. Check for any recent Product Change Notifications (PCN) regarding wafer fab site changes or material updates that may affect long-term sourcing stability.

Selection Notes

Select this component when a low-power CMOS timer with a wide voltage supply range is required. Ensure the external timing components can support the 100 kHz maximum frequency limit. Verify that the 14-TSSOP package size fits the available PCB area and that the thermal performance is adequate for the expected ambient temperatures within the -55 °C to +125 °C range.

Part Context

This part belongs to the CD4541 family of programmable timers. The 'B' designation typically refers to the enhanced version of the standard CD4541. The 'PWR' suffix denotes the 14-TSSOP package type. The 'G4' suffix generally signifies RoHS compliance and lead-free construction, consistent with Texas Instruments' product naming conventions for environmental compliance.

Replacement Considerations

Direct pin-to-pin replacements include the CD4541BPWR. Other variants in the CD4541 series such as CD4541BM or CD4541BMT offer similar functionality but differ in package type (SOIC vs TSSOP). Verify electrical parameters and package dimensions before substituting.
