CD4020BCM

Counter Dividers Overview

The CD4020BCM is a 14-stage ripple carry binary counter manufactured by onsemi in a 16-lead Small Outline Integrated Circuit (SOIC) package. It advances one count on the negative transition of each clock pulse and resets to zero via a logical high at the reset input. The device operates within a supply voltage range of 3.0V to 15V, with an operating temperature range of -55°C to +125°C. At VDD = 10V, it supports a typical maximum clock frequency of 8 MHz.

Counter Dividers Feature Summary

• Features a Schmitt trigger clock input for enhanced noise immunity.
• Provides asynchronous reset capability independent of the clock signal.
• Offers low power consumption compatible with TTL logic families.

Counter Dividers Applications

• RC oscillator circuits
• Crystal oscillator configurations
• Timing and counting applications

Counter Dividers Procurement Notes

Verify that the component matches the specific SOIC-16 package designation M16A. Confirm the manufacturer origin as Fairchild Semiconductor or its successor entities. Ensure the part number suffix BCM corresponds to the narrow SOIC form factor rather than the plastic dual-in-line variant.

Counter Dividers Selection Notes

Select this component when a 14-bit asynchronous counter is required for digital timing sequences. Consider the wide supply voltage tolerance and Schmitt trigger inputs for environments requiring robust noise rejection. Verify that the 16-pin surface mount footprint aligns with the target PCB layout constraints.

Counter Dividers Part Context

This integrated circuit belongs to the CD4000B series of CMOS logic devices. It functions alongside related counters such as the CD4040BC and CD4060BC within the same family documentation. The device utilizes standard CMOS technology to provide reliable binary counting operations across industrial temperature ranges.
