MC14541BDTR2 [Onsemi]

The MC14541B is a programmable timer featuring a 16-stage binary counter, integrated RC oscillator (with ±2% temperature accuracy), automatic power-on reset, and output control logic. It operates as a 2n frequency divider or single-transition timer with outputs of 28, 210, 213, or 216. Key capabilities include positive-edge clock triggering, oscillator bypass for external clocks, independent master reset, Q/Q select for output polarity control, reset-disables-oscillator for zero power dissipation, and clock conditioning for slow rise/fall times. Supply voltage ranges from 3.0V to 18V (auto-reset enabled) or 8.5V to 18V (auto-reset disabled). Automotive-grade (NLV) and RoHS compliant.
