MC74HC393F

Counter Dividers Overview

The MC74HC393F is a dual 4-bit binary counter integrated circuit manufactured by onsemi. It operates within a supply voltage range of 2 V to 6 V and supports a maximum counting rate of 50 MHz. The device features two independent 4-bit ripple counters with asynchronous reset inputs and negative edge-triggered clocking. Designed for surface-mount applications, it is housed in a 14-SOIC package. The component functions reliably across an extended industrial temperature range from -55°C to 125°C.

Counter Dividers Feature Summary

• Dual independent 4-bit binary up-counter architecture
• Asynchronous reset functionality for immediate clearing
• Negative edge-triggered clock input operation
• Extended industrial temperature rating capability

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting sequences in digital systems
• Timing control logic generation
• Event counting applications

Counter Dividers Procurement Notes

Verify the specific suffix 'F' corresponds to the 14-SOIC package configuration as documented in official datasheets. Confirm RoHS compliance status, as some sources indicate non-applicable or varying standards depending on manufacturing date. Ensure the ordering part number matches the required lead-free specifications and moisture sensitivity level requirements for your assembly process.

Counter Dividers Selection Notes

Select this component when a dual-channel binary counting solution is required within the HC logic family voltage constraints. The 50 MHz speed rating suits moderate-frequency digital applications. Consider the 14-SOIC footprint for PCB layout compatibility. Verify that the asynchronous reset behavior aligns with system timing requirements compared to synchronous alternatives.

Counter Dividers Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by onsemi. It is functionally compatible with other manufacturers' 74HC393 equivalents. The device is part of a broader portfolio of binary counters and dividers designed for general-purpose digital logic applications requiring low power consumption and wide operating voltage ranges.

Counter Dividers Replacement Considerations

Equivalent parts include the SN74HC393 from Texas Instruments and the CD74HC393 from Harris Semiconductor. These components share identical logical functionality and pinouts. Verify package dimensions and electrical characteristics against specific application needs before substitution.
