SN74LS593DW

Counter Dividers Overview

The SN74LS593DW is an obsolete octal D-type flip-flop with a clocked output, manufactured by Texas Instruments. It operates within the LS logic series and utilizes bipolar technology. The component is housed in a 20-pin SOIC (DW) package. It functions as a shift register with serial-in and parallel-out capabilities, featuring a dedicated serial output line. The device supports a supply voltage range of 4.75 V to 5.25 V and operates at temperatures between 0°C and +70°C.

Counter Dividers Feature Summary

• Octal D-type flip-flops with clocked outputs
• Serial-in, parallel-out shift register configuration
• Bipolar LS logic family implementation

Counter Dividers Applications

• Data storage in digital systems
• Parallel-to-serial data conversion
• Shift register applications requiring clocked outputs

Counter Dividers Procurement Notes

Verify obsolescence status directly with Texas Instruments before design finalization. Confirm availability of active replacements such as the SN74LS593DWR or SN74LS593N. Ensure current inventory sources are authorized distributors to avoid counterfeit components. Review datasheet SDLS004 for updated electrical characteristics and pin configurations prior to integration.

Counter Dividers Selection Notes

Select this component only if legacy compatibility with the SN74LS593 architecture is required. Consider the SN74LS593DWR for surface-mount production needs, as the DW variant is obsolete. Evaluate power consumption and speed requirements against other LS series alternatives. Verify that the 20-pin SOIC footprint matches the existing PCB layout constraints.

Counter Dividers Part Context

This part belongs to the SN74LS593 family of octal D-type flip-flops. It provides a solution for storing eight bits of data with synchronized output control. The LS series offers standard switching speeds suitable for general-purpose logic applications. The device integrates clocked outputs to prevent glitches during state transitions.

Counter Dividers Replacement Considerations

The SN74LS593DWR is an active production replacement offering identical functionality in a tape-and-reel format. The SN74LS593N serves as a through-hole alternative. Both options maintain the same logical operations and pinout compatibility.
