CD4520BMG4

Counter Dividers Overview

The CD4520BMG4 is a CMOS dual binary up-counter integrated circuit manufactured by Texas Instruments. It belongs to the CD4500B series and features two independent synchronous counters, each with four bits. The device operates within a supply voltage range of 3 V to 18 V and supports a maximum clock frequency of 8 MHz at 10 V. It utilizes Schmitt-trigger inputs on the clock lines for noise immunity and includes asynchronous reset functionality. The component is housed in a 16-pin SOIC package and is rated for operation from -55°C to +125°C.

Counter Dividers Feature Summary

• Dual independent four-bit synchronous binary up-counters
• Schmitt-trigger clock inputs for enhanced noise rejection
• Asynchronous reset capability for both counter sections
• Wide operating voltage range supporting 3 V to 18 V

Counter Dividers Applications

• Digital timing and sequencing circuits
• Frequency division networks
• Event counting systems
• Binary-coded decimal (BCD) generation

Counter Dividers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the SOIC-16 package dimensions match design constraints. Ensure the ordering part number matches the exact functional specification required, as suffixes may denote packaging or environmental variations without changing core logic.

Counter Dividers Selection Notes

Select this component when dual independent synchronous counting is required in a single package. The CD4520B offers a direct alternative to the CD4518B, distinguished by its Schmitt-trigger clock inputs which provide superior noise immunity compared to standard level-sensitive clocks. Verify that the 8 MHz maximum frequency meets system timing requirements.

Counter Dividers Part Context

This part is part of the Texas Instruments CD4500B family of high-speed CMOS logic devices. The CD4520B specifically provides dual up-counters, contrasting with the CD4518B which lacks Schmitt triggers. It is designed for general-purpose digital applications requiring reliable binary counting in industrial environments.

Counter Dividers Replacement Considerations

The CD4518B is a functionally similar dual up-counter but lacks Schmitt-trigger clock inputs. Cross-reference with MC14520BDWR2G from onsemi for pin-compatible alternatives.
