CD4520BPWR

Counter Dividers Overview

The CD4520BPWR is a dual binary up-counter integrated circuit manufactured by Texas Instruments, belonging to the 4000B series. It features two independent synchronous counters, each with four bits of capacity. The device operates within a supply voltage range of 3 V to 18 V and supports a maximum counting rate of 8 MHz. It utilizes a 16-TSSOP surface-mount package and functions reliably across an extended temperature range from -55°C to 125°C.

Counter Dividers Feature Summary

• Contains two independent synchronous binary up-counters
• Features asynchronous reset capability for immediate clearing
• Includes Schmitt trigger inputs on clock lines for noise immunity

Counter Dividers Applications

• Digital frequency division circuits
• Binary-coded decimal (BCD) counting systems
• Timing and sequencing logic control

Counter Dividers Procurement Notes

Verify the specific suffix 'PWR' confirms the TSSOP-16 package and tape-and-reel shipping format. Ensure compatibility with the 4000B series logic family requirements. Confirm RoHS3 compliance status if required by assembly standards. Validate that the operating voltage and temperature ranges meet the target application specifications before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a dual-channel synchronous binary counter is required in a compact surface-mount form factor. It is suitable for designs needing independent counting channels within a single package. Consider the 8 MHz maximum frequency limit for high-speed applications. Verify that the 16-TSSOP footprint aligns with the PCB layout constraints.

Counter Dividers Part Context

This part is part of the CD4520B logic family, which provides dual 4-bit synchronous binary counters. It serves as a CMOS alternative to older TTL logic families, offering lower power consumption and wider voltage tolerance. The device is widely used in general-purpose digital logic applications requiring reliable binary counting operations.
