SN74LS593DWR

Counter Dividers Overview

The SN74LS593DWR is an octal D-type flip-flop with a 3-state output, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a temperature range of 0°C to +70°C. The device features a propagation delay of 18 ns at 5 V, with low-level output current of 32 mA and high-level output current of -2.6 mA. It is housed in a 20-pin SOIC (DW) package.

Counter Dividers Feature Summary

• Octal D-type flip-flop architecture with independent data inputs
• Three-state outputs for bus-driven applications
• Compatible with standard TTL logic levels

Counter Dividers Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations
• General-purpose storage elements in digital systems

Counter Dividers Procurement Notes

Verify the active status and RoHS compliance directly with Texas Instruments or authorized distributors before procurement. Confirm that the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your system's environmental conditions. Check for any specific marking codes or lot traceability requirements relevant to your manufacturing process.

Counter Dividers Selection Notes

Select this component when an octal storage element with three-state capability is required within the LS logic family. Consider the 18 ns propagation delay and 32 mA drive strength for timing and load analysis. Verify compatibility with existing TTL input thresholds and power supply constraints. Evaluate the SOIC-20 package against available board space and assembly methods.

Counter Dividers Part Context

This part belongs to the SN74LS593 series of octal D-type flip-flops. It is distinct from the SN74LS592, which lacks the three-state output feature. The 'DWR' suffix indicates the SOIC-20 tape-and-reel packaging variant. It is part of the broader SN54/74LS logic family designed for standard 5V operation.

Counter Dividers Replacement Considerations

SN74LS593DW is the tube version of the same component.
