MC74HC393D

Counter Dividers Overview

The MC74HC393D is a dual 4-bit binary counter from the onsemi 74HC series, housed in a 14-SOIC surface-mount package. It operates within a supply voltage range of 2 V to 6 V and supports an asynchronous reset function with up-counting logic. The device utilizes negative edge-triggered flip-flops and features a maximum counting rate of 50 MHz. Designed for industrial applications, it functions reliably across a wide temperature range from -55°C to 125°C.

Counter Dividers Feature Summary

• Dual independent 4-bit binary counters integrated into a single package
• Asynchronous active-low reset capability for immediate state clearing
• Negative edge-triggered clock input for precise timing control
• Wide operating voltage range supporting low-power digital systems

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting sequences in measurement devices
• Timing control logic in industrial automation
• Address decoding in memory systems

Counter Dividers Procurement Notes

Verify the specific suffix 'D' indicates the 14-SOIC package variant rather than other packaging options like TSSOP or DIP. Confirm RoHS compliance status as datasheets may list variations. Ensure the ordering code matches the required lead time and moisture sensitivity level for your assembly process. Cross-reference the manufacturer part number against distributor listings to avoid confusion with similar HC series components.

Counter Dividers Selection Notes

Select this component when a dual-channel binary counting solution is required in a compact surface-mount form factor. The 74HC logic family offers compatibility with standard CMOS interfaces while maintaining low power consumption. Consider the 50 MHz speed rating for high-frequency applications and verify that the 2 V to 6 V supply range aligns with your system's power rails. The wide temperature range makes it suitable for harsh environments.

Counter Dividers Part Context

This part belongs to the widely adopted 74HC393A logical family, known for its robust performance in general-purpose digital logic applications. The 'MC' prefix denotes onsemi manufacturing standards, ensuring consistency with industry specifications. As a standard product, it integrates seamlessly into designs requiring reliable binary counting without complex configuration requirements.

Counter Dividers Replacement Considerations

Direct substitutes include the MC74HC393ADR2G (SOIC-14) and generic 74HC393 equivalents from other manufacturers such as Toshiba. Verify pinout compatibility and electrical characteristics before substitution. Note that some variants may differ in packaging style or temperature range specifications.
