74VHC393M

Counter Dividers Overview

The onsemi 74VHC393M is a dual 4-bit binary counter fabricated with silicon gate CMOS technology. It contains two independent counters, each capable of counting up to eight bits or performing frequency division. The device operates within a supply voltage range of 2.0 V to 5.5 V and features asynchronous clear inputs that reset outputs to low regardless of other states. It transitions on the negative clock edge and includes input protection allowing operation between 5V and 3V systems.

Counter Dividers Feature Summary

• Contains two independent 4-bit binary counters in a single package
• Asynchronous high-level clear function resets all outputs
• Negative-going clock pulse triggers state changes
• Input protection circuit enables interfacing between mismatched supply voltages

Counter Dividers Applications

• Frequency division circuits
• Digital counting applications
• Interfacing 5V to 3V logic systems
• Battery backup system integration

Counter Dividers Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status via official documentation. Ensure ordering suffixes match required packaging formats such as tape and reel variants. Check for lead-free certification per JEDEC standards before procurement.

Counter Dividers Selection Notes

Select this component when dual independent counting capabilities are required in a compact form factor. Consider the 74VHC series for high-speed performance comparable to Bipolar Schottky TTL while maintaining low power dissipation. Verify operating temperature ranges meet environmental requirements.

Counter Dividers Part Context

This part belongs to the 74VHC logic family, representing advanced high-speed CMOS technology. Originally manufactured by Fairchild Semiconductor, it maintains pin and function compatibility with equivalent 74HC393 devices. The M14A package designation indicates a 14-lead Small Outline Integrated Circuit conforming to JEDEC MS-012 standards.

Counter Dividers Replacement Considerations

The 74HC393 serves as a functionally compatible alternative within the same logic family. Verify voltage levels and speed specifications against application requirements when substituting.
