At the 100 kHz max clock input, that gives you a time-out period of about 655 ms per cycle before the output toggles. The 3 V to 20 V supply range is unusually wide for a CMOS timer — it lets you run the same part off a 3.3 V logic rail or a 12 V industrial supply without a regulator. ## Package and board-fit for a field swap No hot-air station needed; a fine-tip iron and some wick will get the old one off, and the pin pitch is wide enough that bridging is unlikely if you go slow. The orientation mark is pin 1 dimple on the top, which is visible under a desk lamp. ## Lifecycle and compliance — still a current part This is a standard catalog part, not a niche or end-of-life line — you can spec it into a new BOM without worrying about a last-time-buy window closing.","metaTitle":"Texas Instruments CD4541BM Programmable Timer, 100kHz","metaDescription":"Active Texas Instruments CD4541BM programmable timer IC, 65536 count, 100kHz max, 3V-20V supply, -55 to 125°C, 14-SOIC.
