SN74LS595D

Shift Registers Overview

The SN74LS595D is an 8-bit serial-in, serial or parallel-out shift register manufactured by Texas Instruments. It belongs to the SN74LS logic family and utilizes bipolar technology. The device features three-state outputs and is housed in a 16-pin SOIC package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a propagation delay of 35 ns. The component functions across a temperature range of 0°C to +70°C.

Shift Registers Feature Summary

• Provides serial-to-serial and serial-to-parallel data conversion capabilities
• Features three-state outputs for bus-driven applications
• Utilizes standard LS logic family characteristics

Shift Registers Applications

• Data storage and buffering in digital systems
• Parallel output expansion for microcontrollers
• Display driver interfaces requiring serial input

Shift Registers Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-16 package configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating environment remains within the specified 0°C to +70°C temperature range. Validate that the 4.75 V to 5.25 V power supply constraints are met for reliable operation.

Shift Registers Selection Notes

Select this component when bipolar LS logic compatibility is required with three-state output control. Consider the 16-pin SOIC form factor for surface-mount assembly needs. Evaluate the 35 ns propagation delay against system timing requirements. Ensure the design accommodates the narrow 5V supply voltage tolerance typical of the LS series.

Shift Registers Part Context

This part is a member of the SN74LS595 series, which includes variants like SN74LS595DR and SN74LS595DG4. It differs from HCS and AHC families by using bipolar technology and narrower voltage ranges. The 'D' suffix specifically denotes the SOIC-16 package type used in this designation.

Shift Registers Replacement Considerations

SN74LS595D is listed as a recommended replacement for the discontinued SN74LS595DG4.
