CD4541BNSRG4

Overview

The CD4541BNSRG4 is a CMOS programmable timer manufactured by Texas Instruments, belonging to the 4000/14000/40000 series. It features a high voltage rating of 20V and operates within a supply voltage range of 3V to 18V. The device utilizes an asynchronous negative-edge triggered architecture with a 14-bit up-counting direction. Key functional inputs include clock, reset, load, and three frequency select pins (FREQ SELECT A, B, C) for configuring timing intervals. It is housed in a 16-pin SOIC package.

Feature Summary

• CMOS Programmable Timer with 14-bit binary counter
• High Voltage Rating: 20V maximum
• Asynchronous Negative-Edge Triggered Operation
• Three Frequency Select Pins for Timing Configuration

Applications

• Timing circuits requiring programmable intervals
• Frequency division applications
• Pulse generation systems

Part Context

The CD4541BNSRG4 is part of the CD4541B family of CMOS programmable timers. The 'G4' suffix indicates lead-free packaging compliant with RoHS standards. It is functionally compatible with other variants such as CD4541BE and CD4541BCMX_NL, though package types may differ.

Replacement Considerations

Public confirmed substitute part numbers include CD4541BE and CD4541BCMX_NL. Verify pin compatibility and package type when substituting.
