M74HC390D

Counter Dividers Overview

The M74HC390D is a dual four-bit synchronous counter integrated circuit manufactured by onsemi. It operates within a supply voltage range of 2V to 6V and supports clock frequencies up to 50 MHz. The device features asynchronous reset functionality and negative-edge triggering. Designed for surface-mount applications, it utilizes a 16-pin SOIC package with dimensions of approximately 10mm length, 4mm width, and 1.5mm height. The component functions reliably across an extended industrial temperature range from -55°C to +125°C.

Counter Dividers Feature Summary

• Dual independent four-bit binary counting architecture
• Asynchronous reset capability for immediate state clearing
• Negative-edge triggered operation for precise timing control
• Extended industrial temperature rating for harsh environments

Counter Dividers Applications

• Digital frequency division circuits
• Binary sequence generation systems
• Timing and delay control modules
• Industrial process monitoring counters

Counter Dividers Procurement Notes

Verify the specific manufacturer prefix against official onsemi documentation, as standard industry nomenclature typically utilizes MC or MM prefixes for this logic family. Confirm RoHS compliance status and moisture sensitivity level directly with the supplier. Ensure the SOIC-16 package variant matches the required PCB footprint specifications before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when dual independent four-bit counting is required in a compact surface-mount form factor. The wide operating voltage range allows compatibility with various digital logic families. Verify that the asynchronous reset requirement aligns with system design needs. Consider the extended temperature range if the application involves variable environmental conditions.

Counter Dividers Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. The series is characterized by low power consumption and speeds comparable to LSTTL. The specific model integrates two separate four-bit counters within a single package, providing efficient space utilization for complex digital counting applications requiring multiple independent count channels.

Counter Dividers Replacement Considerations

Compatible substitutes include MC74HC390ADG and MC74HC390DR2G from onsemi. Cross-manufacturer equivalents such as SN74HC390 from Texas Instruments may also serve as functional replacements provided pinout and electrical characteristics are verified.
