SN74LS595NSRG4

Shift Registers Overview

The SN74LS595NSRG4 is an 8-bit serial-in, serial or parallel-out shift register manufactured by Texas Instruments. It features a serial input pin and a serial output for cascading multiple devices. The device includes a storage register with parallel outputs that are independent of the shift register inputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 25 MHz. The component is housed in a 16-pin Small Outline (NS) package.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion capabilities
• Includes separate storage register for parallel output control
• Supports cascading via dedicated serial output pin

Shift Registers Applications

• LED display matrix scanning systems
• Industrial control panel indicator arrays
• Data acquisition system expansion modules

Shift Registers Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and tape-and-reel packaging configuration as per manufacturer specifications. Confirm the package type matches the required PCB footprint. Ensure the operating voltage requirements align with the target circuit design before procurement.

Shift Registers Selection Notes

Select this component when 8-bit serial shifting is required with parallel latching functionality. Consider the LS logic family characteristics regarding speed and power consumption relative to HC or HCT alternatives. Verify compatibility with existing microcontroller GPIO interfaces for serial communication protocols.

Shift Registers Part Context

This part belongs to the Texas Instruments SN74LS series of logic integrated circuits. It serves as a fundamental building block for digital systems requiring data serialization and parallel distribution. The NS package variant denotes a standard small outline plastic package suitable for surface mount assembly processes.

Shift Registers Replacement Considerations

SN74LS595N is a compatible leaded alternative from the same manufacturer. SN74HC595 variants offer faster switching speeds but require verification of voltage level compatibility.
