CD4521BMT

Counter Dividers Overview

The CD4521BMT is a CMOS frequency divider integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and supports surface-mount installation in a 16-SOIC package. The device functions as a 24-stage binary counter with asynchronous reset capability, utilizing negative-edge triggered flip-flops. It is designed for high-speed applications with a maximum counting rate of 13 MHz. The component ensures reliable operation across an extended industrial temperature range from -55°C to +125°C.

Counter Dividers Feature Summary

• Provides 24-bit frequency division functionality through cascaded binary stages
• Features asynchronous reset input for immediate state initialization
• Supports high-speed signal processing with a 13 MHz counting rate
• Utilizes negative-edge triggering for precise clock synchronization

Counter Dividers Applications

• Frequency division circuits in digital systems
• Clock signal generation and distribution networks
• Rate multiplier applications requiring binary scaling
• Timing control logic in industrial instrumentation

Counter Dividers Procurement Notes

Verify the specific suffix 'MT' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-SOIC footprint matches the target PCB design constraints. Ensure compatibility with the intended operating voltage range between 3 V and 18 V. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Counter Dividers Selection Notes

Select this component when a single-chip solution for high-ratio frequency division is required. The 24-stage capacity eliminates the need for multiple discrete counters. Consider the wide supply voltage tolerance for systems with varying power rails. The SOIC package offers a balance between pin count and board space efficiency for dense layouts.

Counter Dividers Part Context

This part belongs to the CD4000B series of CMOS logic devices, known for robust performance and low power consumption. It serves as a specialized divider within the broader logic IC portfolio, distinct from standard counters or timers. The device complements other family members like the CD4520 dual binary counter by providing higher division ratios in a compact form factor.

Counter Dividers Replacement Considerations

The CD4521BM96 is listed as a manufacturer-recommended alternative. Other potential substitutes include the HEF4521BT from Nexperia and MC14521BDG from onsemi, though pinout and electrical characteristics should be verified against official datasheets before substitution.
