SN74HC393DR

Counter Dividers Overview

The SN74HC393DR is a dual 4-bit binary counter from the Texas Instruments HC logic family, housed in a 14-pin SOIC package. It operates within a supply voltage range of 2V to 6V and supports an operating temperature range of -40°C to +85°C. The device integrates two independent counters with individual clocks and direct clear inputs. Key electrical specifications include a maximum clock frequency of 25MHz at 4.5V, typical propagation delay of 30ns, and output drive capability of ±4mA at 5V.

Counter Dividers Feature Summary

• Integrates two independent 4-bit binary counters within a single package
• Features direct asynchronous clear inputs for each counter stage
• Provides parallel outputs from each flip-flop for system timing signals
• Compatible with LSTTL loads while maintaining low power consumption

Counter Dividers Applications

• System timing signal generation using submultiples of input count frequency
• Frequency division circuits providing divide-by-256 functionality
• Digital counting applications requiring high-density integration

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the SOIC-14 tape and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level ratings prior to assembly. Ensure the procurement source provides valid traceability documentation consistent with Texas Instruments production data standards.

Counter Dividers Selection Notes

Select this component when design requirements necessitate dual independent 4-bit counters in a surface-mount format. The HC series offers wide voltage flexibility compared to fixed-voltage logic families. Verify that the required clock frequencies remain within the specified limits for the target supply voltage to ensure reliable operation.

Counter Dividers Part Context

This part belongs to the SNx4HC393 family of dual 4-bit binary counters manufactured by Texas Instruments. The 'D' suffix indicates the SOIC package type, while 'R' denotes tape and reel packaging. This family allows designers to reduce component count by integrating two separate counters into one footprint.

Counter Dividers Replacement Considerations

SN74HC393DRG4 is a verified equivalent variant within the same product line.
