Overview
The CD4541BM96, produced by Texas Instruments, is a CMOS programmable timer that integrates a 16-stage binary counter, an oscillator controlled by external R-C components, an automatic power-on reset circuit, and output control logic. This device is part of the CD4541B series and is available in a 14-pin SOIC package. It operates over a wide temperature range of -55°C to 125°C and is designed to meet the requirements of JEDEC Standard No. 13B for B Series CMOS devices.
