MC14521BDR2

Counter Dividers Overview

The MC14521BDR2G is a 24-stage frequency divider manufactured by onsemi in a SOIC-16 package. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports ambient temperatures from -55°C to +125°C. The device features three input modes: crystal oscillator, RC oscillator, or external buffer. Each flip-flop divides the preceding frequency by two, enabling counts up to 2^24 (16,777,216). Outputs for stages 18 through 24 are accessible. Clock inputs trigger on negative edges.
