Maximum oscillator frequency is 100 kHz, setting the shortest time-out period at roughly 0.655 seconds (65536 / 100 kHz). Supply range spans 3 V to 20 V — wide enough to run off a 12 V industrial rail or a 5 V logic supply without a separate regulator. The -55°C to 125°C operating range covers military/aerospace temperature grades, so the timer holds its timing accuracy across the full thermal profile of an engine bay or satellite bus. Housed in a 14-lead TSSOP (4.40 mm width), the surface-mount package suits dense PCB layouts where a through-hole DIP would consume more board area. The 0.65 mm pin pitch is standard for TSSOP-14; the footprint matches the JEDEC MO-153 pattern. ## Design-in note — external RC tolerance and supply decoupling The oscillator frequency is set by an external resistor and capacitor; the 100 kHz maximum is the internal gate delay limit, not the RC time constant. For a 1-second time-out at 65.536 counts, the RC product must be tuned to 65.536 ms — a 100 kΩ resistor and 0.68 µF capacitor lands close, but the capacitor's temperature coefficient directly shifts the interval. A 0.1 µF ceramic decoupling capacitor within 5 mm of the supply pin is recommended; the wide 3–20 V range means the timer can share a rail with relays or solenoids, but a bulk capacitor on the VDD line absorbs the switching transients that would otherwise couple into the oscillator input.","metaTitle":"Texas Instruments CD4541BPW Programmable Timer, 100kHz","metaDescription":"Active-production programmable timer IC from TI. 3V–20V supply, -55°C to 125°C range. 65536-count divider.
