74HCT4520D,112

Counter Dividers Overview

The Nexperia 74HCT4520D,112 is a dual 4-bit internally synchronous binary counter housed in an SO16 (SOT109-1) plastic small outline package. It features two clock inputs per counter (nCP0 and nCP1), 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 4.5 V to 5.5 V, adhering to TTL input levels. It supports multistage counting and frequency division applications across an ambient temperature range of -40 °C to +125 °C.

Counter Dividers Feature Summary

• Dual independent 4-bit synchronous binary counters with separate clock inputs
• Asynchronous master reset functionality for immediate output clearing
• TTL-compatible input logic levels for direct interfacing
• High noise immunity and robust latch-up performance

Counter Dividers Applications

Counter Dividers Selection Notes

Select this component when dual independent 4-bit counting is required within a single package. The HCT variant ensures compatibility with standard TTL logic families, simplifying interface design with existing digital systems. Ensure the application environment remains within the specified -40 °C to +125 °C operating temperature range to maintain guaranteed electrical characteristics.

Counter Dividers Part Context

This part belongs to the 74HC/HCT series of CMOS logic devices manufactured by Nexperia. The 74HCT family specifically bridges the gap between low-voltage CMOS technology and traditional TTL logic standards, offering improved noise margins while maintaining pin compatibility with earlier generations of digital logic components.

Counter Dividers Replacement Considerations

Direct functional equivalents include the 74HC4520D for CMOS-level interfaces or other 74HCT4520 variants from different manufacturers that match the SO16 package and electrical specifications.
