CD4017BMG4

Counter Dividers Overview

The CD4017BMG4 is a CMOS decade counter and divider manufactured by Texas Instruments, belonging to the 4000B series. It features ten decoded outputs that sequentially activate in response to clock pulses. The device operates within a supply voltage range of 3 V to 18 V and supports clock frequencies up to 11 MHz. It utilizes a 16-pin SOIC surface-mount package and functions reliably across an industrial temperature range from -55 °C to +125 °C.

Counter Dividers Feature Summary

• Provides ten mutually exclusive decoded outputs for sequential counting applications
• Includes dedicated carry-out terminal for cascading multiple stages
• Features asynchronous master reset input for immediate state initialization

Counter Dividers Applications

• Digital sequencing and order-of-operations control circuits
• LED display scanning and multiplexing drivers
• Frequency division and digital timing generation

Counter Dividers Procurement Notes

Verify the specific suffix G4 indicates compliance with RoHS directives and lead-free manufacturing standards as per Texas Instruments documentation. Confirm the SOIC-16 package dimensions match the target PCB footprint requirements. Ensure the operating environment remains within the specified -55 °C to +125 °C temperature limits to maintain signal integrity and performance specifications.

Counter Dividers Selection Notes

Select this component when a synchronous decade counter with decoded outputs is required in a surface-mount design. It serves as a direct replacement for standard CD4017BE devices where through-hole packaging is unsuitable. Consider the 11 MHz maximum clock frequency limit when designing high-speed timing circuits to ensure reliable operation without propagation delay errors.

Counter Dividers Part Context

This part belongs to the Texas Instruments 4000B series of CMOS logic devices, which are industry-standard replacements for earlier 4000B family components. The CD4017 variant specifically provides decade counting functionality. The G4 suffix denotes environmental compliance, distinguishing it from older non-compliant variants while maintaining identical electrical and functional characteristics.

Counter Dividers FAQ

What is the function of the Carry Out pin?

The Carry Out pin generates a pulse when the counter reaches its tenth state, allowing multiple CD4017 chips to be cascaded for extended counting sequences.

How does the Master Reset input operate?

The Master Reset is asynchronous; applying a high level to this pin immediately resets all outputs to their inactive state regardless of the clock signal phase.
