74HC4520DB,118

Counter Dividers Overview

The 74HC4520DB,118 is a dual 4-bit internally synchronous binary counter manufactured by Nexperia. It features two clock inputs (nCP0 and nCP1) per counter, allowing either to serve as the clock or enable input. The device includes buffered outputs for all four bit positions and an asynchronous master reset input. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C.

Counter Dividers Feature Summary

• Dual independent 4-bit synchronous binary counters with selectable clock inputs
• Asynchronous master reset functionality independent of clock signals
• CMOS low power dissipation with high noise immunity characteristics

Counter Dividers Applications

• Multistage synchronous counting systems
• Multistage asynchronous counting configurations
• Frequency divider circuits

Counter Dividers Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and availability status. Confirm that the component meets required environmental specifications for the intended operating temperature range. Ensure design compatibility with recommended operating conditions before procurement.

Counter Dividers Selection Notes

Select this component when dual independent 4-bit synchronous counting is required in a single package. Verify logic level compatibility between CMOS and TTL standards if interfacing with other logic families. Consider the SO16 package dimensions for PCB layout constraints and thermal management requirements.

Counter Dividers Part Context

This part belongs to the 74HC4520 family of dual 4-bit synchronous binary counters. It is produced by Nexperia, which acquired the semiconductor division previously associated with NXP. The device is designed for general-purpose digital logic applications requiring reliable binary counting operations.

Counter Dividers Replacement Considerations

The 74HCT4520DB variant serves as a compatible alternative offering TTL-compatible input levels while maintaining identical functional behavior and pinout configuration.
