SN74LS597D

Shift Registers Overview

The SN74LS597D is an eight-bit serial-in or parallel-in, serial-out shift register manufactured by Texas Instruments. It belongs to the SN54/74LS series and operates within a supply voltage range of 4.75 V to 5.25 V. The device features a serial input pin for data shifting and eight parallel output pins. It includes dedicated clock inputs for both storage and shift operations, along with an asynchronous master reset. The component is housed in a 16-pin Small Outline Integrated Circuit (SOIC) package.

Shift Registers Feature Summary

• Supports both serial input and parallel loading configurations for flexible data entry.

Shift Registers Applications

• Serial-to-parallel data conversion in digital systems
• Expansion of I/O ports in microcontroller-based designs
• Data buffering and temporary storage in logic circuits

Shift Registers Procurement Notes

Verify that the specific part number matches the required LS logic family specifications. Confirm the package type corresponds to the design footprint requirements. Ensure compliance with relevant environmental standards such as RoHS if applicable to the manufacturing batch. Cross-reference the manufacturer's documentation for any recent product change notices or obsolescence alerts before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when an eight-bit shift register with parallel load capability is required. The LS series offers standard TTL compatibility suitable for general-purpose logic applications. Consider the operating temperature range and power consumption characteristics relative to the system environment. Verify that the SOIC package dimensions fit the available board space constraints.

Shift Registers Part Context

This device is part of the widely used SN54/74LS logic family, known for its compatibility with standard transistor-transistor logic (TTL) systems. It serves as a fundamental building block for sequential logic circuits requiring data movement and storage functions. The component is designed for reliable operation in commercial and industrial electronic applications.

Shift Registers Replacement Considerations

Check for direct equivalents such as the SN74LS597DG4 variant which may offer different packaging or environmental certifications. Verify functional compatibility with other eight-bit shift registers from the same logic family before substitution.
