CD4541BM96G4

Overview

The CD4541BM96G4 is a CMOS programmable timer circuit manufactured by Texas Instruments. It features a single internal timer with a 14-pin SOIC surface-mount package. The device operates within a supply voltage range of 3V to 20V and supports an operating temperature range from -55°C to +125°C. Key electrical parameters include a maximum propagation delay of 10,500 ns, high-level output current of 4 mA, low-level output current of 4 mA, and a typical operating supply current of 300 µA. The component complies with RoHS standards.

Feature Summary

• CMOS Programmable Timer with 1 internal timer channel
• Wide supply voltage range: 3V to 20V
• Extended industrial temperature range: -55°C to +125°C
• 14-pin SOIC (0.154", 3.90mm wide) surface-mount package

Applications

• General-purpose timing circuits
• Pulse generation applications
• Industrial control systems requiring wide temperature tolerance

Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and environmental specifications as per Texas Instruments documentation. Confirm the package variant matches the required 14-SOIC footprint for PCB layout compatibility. Ensure the operating conditions align with the specified 3V to 20V supply range and -55°C to +125°C temperature limits for the target application environment.

Selection Notes

Select this component when a single-channel programmable timer in a surface-mount package is required. The CD4541BM96G4 is suitable for designs needing operation up to 20V and extended temperature ranges. Compare against through-hole variants like the CD4541BE if board space constraints are not present. Verify that the 10,500 ns maximum propagation delay meets the timing precision requirements of the system.

Part Context

The CD4541BM96G4 belongs to the CD4541B series of CMOS programmable timers. The 'BM' designation typically refers to the SOIC package type, while '96' often denotes specific tape-and-reel packaging configurations. The 'G4' suffix signifies lead-free construction and adherence to specific environmental directives. This part is a surface-mount version of the widely used CD4541 timer family.

Replacement Considerations

The CD4541BMT is a direct functional equivalent in the same 14-SOIC package. Other compatible parts include the CD4541BM without the G4 suffix for non-lead-free requirements, or the CD4541BE for through-hole implementations. Verify pinout and electrical characteristics match before substitution.
