Overview
The CD4541BM is a CMOS programmable timer and oscillator manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 20V and features a maximum frequency rating of 3MHz. The device is housed in a 14-SOIC surface-mount package with a width of 5.30mm. It supports an internal counter of 65,536 steps and includes a reset input for timing control. The component is designed for industrial applications, functioning reliably across a temperature range of -55°C to 125°C.
Feature Summary
- CMOS programmable timer with 65,536 count capacity
- Wide supply voltage operation from 3V to 20V
- Industrial temperature range: -55°C to 125°C
- 14-pin SOIC surface-mount package
Applications
- Programmable time delay circuits
- Frequency division applications
- Watchdog timer implementations

Procurement Notes
Verify the specific suffix 'BM' corresponds to the standard 14-SOIC plastic package variant. Confirm RoHS compliance status as manufacturing updates may alter environmental declarations. Check for active production status versus obsolete listings from previous distributors. Ensure the supplier provides valid traceability documentation for industrial-grade components.
Selection Notes
Select this component when a high-voltage CMOS timer is required in a surface-mount form factor. Compare against the CD4541BE if through-hole DIP packaging is necessary for prototyping. Verify that the 3MHz maximum frequency meets the system clock requirements. Consider the 14-SOIC footprint dimensions during PCB layout planning.
Part Context
The CD4541BM belongs to the CD4500B series of CMOS logic devices. It serves as a direct pin-compatible replacement for equivalent programmable timers from other manufacturers such as onsemi's MC14541 series. The 'BM' designation specifically identifies the Texas Instruments SOIC package variant within the broader CD4541 family.
