CD4020BNSRG4

Counter Dividers Overview

The CD4020BNSRG4 is a binary ripple-carry counter integrated circuit from the Texas Instruments CD4000B series. It features a 14-bit asynchronous up-counter architecture housed in a 16-pin SOIC surface-mount package. The device operates on a supply voltage range of 3 V to 18 V and supports a maximum counting rate of 24 MHz. It utilizes negative-edge-triggered flip-flops for data latching and includes an asynchronous reset function. The component is rated for operation within an extended temperature range of -55°C to +125°C.

Counter Dividers Feature Summary

• Implements a 14-bit asynchronous binary up-counter with ripple-carry output capability
• Features negative-edge-triggered clock inputs for precise timing control
• Includes an asynchronous reset input for immediate state initialization
• Supports wide operating voltage ranges suitable for diverse logic environments

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting sequences in digital systems
• Timing and delay generation applications
• Ripple-carry cascading for extended bit-counting operations

Counter Dividers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS standards during procurement. Confirm the package designation matches the required 16-SOIC footprint for PCB layout compatibility. Ensure the ordering part number aligns with the manufacturer's current production status, as suffixes may denote regional or environmental variations that do not alter electrical functionality.

Counter Dividers Selection Notes

Select this component when a 14-bit count capacity is required in a surface-mount design. The 16-pin SOIC package offers a compact solution compared to through-hole alternatives like the DIP-16 variant. Consider the 24 MHz maximum frequency limit against system clock speeds. Verify that the asynchronous reset requirement fits the system's power-up sequence needs.

Counter Dividers Part Context

This part belongs to the CD4000B series of CMOS logic devices, which are standard components for general-purpose digital logic. The CD4020B specifically provides higher bit-depth counting than the 7-bit CD4024 or 12-bit CD4040. The 'G4' suffix typically denotes Green/RoHS-compliant manufacturing, distinguishing it from older non-compliant versions while maintaining pinout and electrical equivalence.

Counter Dividers Replacement Considerations

The CD4020BNSR is the direct commercial equivalent without the environmental suffix. For through-hole requirements, the CD4020BE serves as a compatible alternative. Designers should verify that any substitute maintains the same 16-pin SOIC footprint if board space is constrained.
