SN74LS673DW

Shift Registers Overview

The SN74LS673DW is a serial-in parallel-out shift register from the Texas Instruments LS logic family. It features a 16-bit architecture with right-shift direction capability and true outputs. The device utilizes a 24-pin SOIC surface-mount package and operates within a supply voltage range of 4.75 V to 5.25 V. It supports a maximum clock frequency of 35 MHz at nominal voltage, with a propagation delay of 40 ns. The component functions in commercial temperature environments ranging from 0°C to +70°C.

Shift Registers Feature Summary

• Serial input data converted to parallel output across 16 bits
• Right-shift direction control for sequential data processing
• True output polarity providing non-inverted signals
• Three-state output capability for bus line interfacing

Shift Registers Applications

• Data storage registers in digital systems
• Parallel-to-serial conversion circuits
• Shift register chains for extended bit handling
• Memory buffer applications requiring registered outputs

Shift Registers Procurement Notes

Verify the specific suffix 'DW' confirms the SOIC-24 surface mount package variant. Confirm RoHS compliance status through official manufacturer documentation as legacy LS series parts may vary. Ensure the operating environment remains within the specified commercial temperature limits of 0°C to +70°C for reliable performance.

Shift Registers Selection Notes

Select this component when a 16-bit serial-in parallel-out function is required with three-state outputs. The LS logic family offers standard TTL compatibility. Consider the SOIC-24 package for surface mount assembly requirements. Verify that the 35 MHz maximum clock speed meets the system timing constraints.

Shift Registers Part Context

This part belongs to the SN74LS67x series of shift registers manufactured by Texas Instruments. It is designed for general-purpose digital logic applications requiring data shifting and storage capabilities. The LS series provides low power dissipation compared to standard TTL while maintaining compatible logic levels.

Shift Registers Replacement Considerations

Compatible substitutes include other SN74LS673 variants such as the DIP package version SN74LS673N or equivalent parts from other manufacturers offering identical 16-bit serial-in parallel-out functionality with three-state outputs.
