MC14521BDG

Counter Dividers Overview

The MC14521BDG is a 24-stage frequency divider and oscillator manufactured by onsemi in a 16-pin SOIC package. It consists of a chain of flip-flops where each stage divides the preceding frequency by two, enabling counts up to 2^24 (16,777,216). The device supports three input modes: crystal oscillator, RC oscillator, or external buffer. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and functions across an ambient temperature range of -55 °C to +125 °C.

Counter Dividers Feature Summary

• Supports crystal, RC, and external oscillator input configurations

Counter Dividers Procurement Notes

Verify the specific ordering suffix to confirm package type and shipping configuration. Confirm whether the part requires automotive qualification standards such as AEC-Q100 compliance. Check current availability status as some variants may be discontinued. Ensure the selected component meets RoHS and Pb-Free requirements if applicable to the design specifications.

Counter Dividers Selection Notes

Select this component when a high-count frequency divider or integrated oscillator solution is required. Consider the operating voltage range and temperature specifications against system constraints. Evaluate the need for external components like crystals or capacitors based on the chosen oscillator mode. Verify that the package dimensions fit the available PCB space.

Counter Dividers Part Context

This device belongs to the MC14521B series of CMOS logic components designed for frequency division and timing applications. It provides a compact solution for generating precise clock signals or dividing existing frequencies in digital systems. The integration of oscillator capabilities reduces the need for separate timing components.

Counter Dividers Replacement Considerations
