74HC4520DB,112

Counter Dividers Overview

The 74HC4520DB,112 is a dual 4-bit internally synchronous binary counter manufactured by Nexperia. It features two clock inputs (nCP0 and nCP1) per counter, buffered outputs from all four bit positions (nQ0 to nQ3), and an asynchronous master reset input (nMR). The device operates within a supply voltage range of 2.0 V to 6.0 V. Propagation delay from clock to output ranges from 22 ns to 240 ns depending on voltage. Maximum operating frequency reaches 69 MHz at 6.0 V. Input levels are CMOS compatible.

Counter Dividers Feature Summary

• Dual independent 4-bit synchronous binary counters with separate clock inputs
• Asynchronous master reset function that clears outputs regardless of clock state
• Buffered outputs for all four bit positions to maintain signal integrity
• High noise immunity and low power dissipation characteristics

Counter Dividers Applications

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

Counter Dividers Procurement Notes

Verify the specific ordering suffix '112' corresponds to the SO16 package variant as defined in the official datasheet. Confirm current production status directly with the manufacturer or authorized distributors, as availability may vary. Ensure the design environment supports the specified temperature range and voltage requirements before finalizing procurement.

Counter Dividers Selection Notes

Select this component when dual independent 4-bit counting capability is required within a single package. The dual clock input architecture allows flexible triggering modes using either positive or negative edges. Verify that the system voltage falls within the 2.0 V to 6.0 V operational range. Consider the propagation delay specifications relative to the maximum system clock frequency to ensure timing compliance.

Counter Dividers Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It is pin-compatible with other standard logic families but offers improved switching speeds and lower power consumption compared to older technologies. The device is designed for general-purpose digital applications requiring reliable binary counting functions in compact surface-mount packages.

Counter Dividers Replacement Considerations

The 74HCT4520DB,112 serves as a TTL-level compatible alternative within the same package. Other variants such as the 74HC4520PW,118 offer the same functionality in a TSSOP16 package. Cross-referencing pinouts and electrical characteristics is essential when substituting with non-Nexperia equivalents.
