SN74HC393NS

Counter Dividers Overview

The SN74HC393N is a dual 4-bit binary counter in a 14-pin PDIP package. It operates on a supply voltage of 2V to 6V and supports frequencies up to 60 MHz. The device contains two independent counters, each with parallel outputs (QA through QD) and direct clear inputs. It features low power consumption and can drive up to 10 LSTTL loads.

Counter Dividers Feature Summary

• Dual 4-bit binary counters with individual clocks
• Direct clear for each 4-bit counter
• Parallel outputs from each counter stage

Counter Dividers Applications

• System timing signals
• Frequency division
• Digital counting circuits

Counter Dividers Procurement Notes

Verify the manufacturer part number matches SN74HC393N exactly. Confirm the package type is PDIP-14. Check RoHS compliance status if required by project specifications. Ensure the operating temperature range meets system requirements.

Counter Dividers Selection Notes

Select this component when dual independent 4-bit binary counting is needed in a single package. It is suitable for applications requiring divide-by-256 functionality or multiple timing signals derived from a single clock source. Verify voltage compatibility with the system logic levels.

Counter Dividers Part Context

This device belongs to the Texas Instruments HC series of logic integrated circuits. It provides high-speed CMOS performance with standard TTL-compatible input and output characteristics. The PDIP-14 package allows for through-hole mounting on printed circuit boards.

Counter Dividers Replacement Considerations

SN74HC393NE4 is an equivalent lead-free variant.
