Programmable timer with 65536-count divider
The CD4541BMT from Texas Instruments is a programmable timer IC in the Clock & Timing ICs family, built around a 65536-count binary counter that divides the internal or external oscillator frequency to produce a programmable time interval.
14-SOIC package — rework and board-fit
The 1.27mm pin pitch gives good solder-joint visibility and allows hand rework with a standard fine-tip iron or hot-air pencil without cooking adjacent components. Pin 1 is clearly marked by a chamfered corner and a dot on the package top — no ambiguity when orienting it for reflow or replacement. The 14-SOIC footprint is common across many TI logic and timer parts, so the board layout is well established.
Texas Instruments lists this part as active, so it is available through authorized distribution channels.
