The CD4541BNSR is a programmable timer IC from Texas Instruments, part of the CD4000 logic family, in a 14-SOIC surface-mount package. It integrates a 65536-count binary counter, a built-in oscillator, and a control logic block that allows the output to toggle after a programmed number of clock cycles. The operating temperature range of -55°C to 125°C qualifies it for industrial and military-temperature applications, including engine-bay electronics and outdoor telecom.
