SN74HC393ANS

Counter Dividers Overview

The SN74HC393ANS is a dual 4-bit binary counter from Texas Instruments' HC logic family, housed in a 14-pin SOIC package. It operates on a supply voltage of 2 V to 6 V with an operating temperature range of -40°C to +85°C. The device features asynchronous reset and negative-edge clocking for each independent 4-bit counter. It provides buffered inputs and outputs capable of driving up to 10 LSTTL loads. Typical propagation delay is 13 ns at 5 V, with maximum quiescent current of 80 µA.

Counter Dividers Feature Summary

• Dual independent 4-bit binary counters with common reset functionality
• Negative-edge triggered clocking for precise timing control
• Buffered inputs to reduce loading effects on preceding stages

Counter Dividers Applications

• Digital frequency division circuits
• System timing signal generation
• Binary counting applications in embedded systems

Counter Dividers Procurement Notes

Verify the 'ANS' suffix indicates the SOIC-14 package variant when ordering. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the supplier provides original TI packaging to guarantee authenticity. Cross-reference the datasheet revision date to ensure compatibility with design requirements.

Counter Dividers Selection Notes

Select this component when dual independent 4-bit counting is required in a single package. The HC series offers high-speed operation suitable for general-purpose digital logic. Consider the SOIC package for surface-mount assembly needs. Verify voltage levels match the system's 2V to 6V operational range.

Counter Dividers Part Context

This part belongs to the SN74HC393 family of dual 4-bit binary counters. It is functionally compatible with other 74HC393 variants from different manufacturers, provided pinouts and electrical characteristics align. The 'ANS' designation specifically identifies the Texas Instruments SOIC-14 package version.

Counter Dividers Replacement Considerations

SN74HC393N (PDIP-14 package) serves as a direct functional substitute with identical logic but different physical mounting. SN74HC393DR is another TI variant in SOIC-8 or similar packages; verify pinout compatibility before substitution.
