SN74LS323DW

Shift Registers Overview

The SN74LS323DW is an 8-bit universal shift/storage register manufactured by Texas Instruments in a 20-pin SOIC package. It operates within a DC supply voltage range of 4.75V to 5.25V and supports a maximum clock frequency of 40 MHz. The device features parallel-in/parallel-out capabilities with serial input options, providing eight data outputs capable of driving up to 8 mA. Propagation delay is specified at 27.0 ns, with an operating temperature range from 0°C to 70°C.

Shift Registers Feature Summary

• Universal shift and storage functionality supporting multiple data transfer modes
• Parallel-in/parallel-out configuration for simultaneous data access
• Positive-edge triggered operation synchronized with clock signals

Shift Registers Applications

• Data buffering in digital logic circuits
• Serial-to-parallel conversion tasks
• General-purpose shift register applications

Shift Registers Procurement Notes

Verify the specific suffix 'DW' indicates the 20-pin SOIC package variant. Confirm RoHS compliance status as documentation may vary by production batch. Ensure the operating environment remains within the specified 0°C to 70°C temperature range for reliable performance. Cross-reference the manufacturer's latest datasheet for any updates to electrical characteristics or pin configurations before final integration.

Shift Registers Selection Notes

Select this component when an 8-bit storage solution with both serial and parallel interfaces is required. The LS series offers standard speed suitable for general logic applications. Consider the 20-pin SOIC footprint for PCB layout compatibility. Verify that the 5V logic level requirements match the system design constraints.

Shift Registers Part Context

This part belongs to the Texas Instruments SN74LSxx logic family, specifically designed for shift register functions. It serves as a universal shift/storage register, distinct from simple D-type flip-flops like the SN74LS273 or basic OR gates like the SN74LS32. The DW suffix denotes the plastic small-outline integrated circuit package type.

Shift Registers Replacement Considerations

Compatible substitutes include other SN74LS323 variants such as SN74LS323N (PDIP) or SN74LS323DWR (tape and reel). Verify package dimensions and pinout compatibility before substitution.
