SN74HC393ANSR

Counter Dividers Overview

The SN74HC393ANSR is a dual 4-bit binary counter from the Texas Instruments HC logic family. It integrates two independent counters, each featuring parallel outputs and dedicated clear (CLR) and clock (CLK) inputs. The device operates on a supply voltage range of 2 V to 6 V and supports asynchronous reset functionality. Designed for surface-mount applications in 14-SOIC packages, it provides up/down counting capabilities with negative-edge triggering. The component ensures reliable performance across an industrial temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Dual independent 4-bit binary counters within a single package
• Asynchronous clear input for immediate reset of each counter stage
• Negative-edge triggered clocking mechanism for precise timing control
• Parallel output configuration enabling frequency division by any sub-multiple

Counter Dividers Applications

• Digital frequency division circuits
• System timing signal generation
• Binary counting sequences in embedded systems
• Event counting applications requiring independent channels

Counter Dividers Procurement Notes

Verify the specific suffix 'A' against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics, as variations may exist between standard and advanced variants. Ensure the SOIC-14 package dimensions match the target PCB footprint requirements. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement decisions.

Counter Dividers Selection Notes

Select this component when dual independent counting channels are required within a limited board space. The HC series offers high noise immunity and low power consumption suitable for general-purpose digital logic. Consider the 2V to 6V operating range for flexibility in various supply voltage environments compared to fixed-voltage logic families.

Counter Dividers Part Context

This part belongs to the SN74HC393 family of dual 4-bit binary counters manufactured by Texas Instruments. It is part of the broader 74HC logic series, known for high-speed operation and CMOS technology. The 'NSR' suffix indicates a surface-mount SOIC package with tape-and-reel packaging, distinguishing it from through-hole or other package variants within the same functional family.

Counter Dividers Replacement Considerations

SN74HC393DR: Surface-mount variant with identical logic function but different package width. SN74HC393N: Through-hole DIP-14 package equivalent. SN74HC393NSR: Standard SOIC-14 variant without the 'A' designation.
