Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LS595DG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: Shift Register (8-bit, single element)
• Output Configuration: Tri-State output
• Functional Capability: Serial-to-parallel and serial output modes
• Supply Voltage Range: 4.75V ~ 5.25V
• Operating Temperature Range: 0°C ~ 70°C
• Package Type: 16-SOIC surface mount
• Electrical and mechanical pin compatibility

The SN74LS595D meets all substitution criteria as a direct functional equivalent within the 74LS series base product family.

Parameter Comparison

Engineering Selection Recommendations

The SN74LS595D is a direct substitute for the SN74LS595DG4 based on identical electrical specifications, functional capability, and package configuration. Both components are ROHS3 compliant and maintain equivalent moisture sensitivity ratings. The SN74LS595D carries a Last Time Buy status, indicating limited future availability. For applications requiring the SN74LS595 shift register function, component selection should prioritize the SN74LS595D while inventory remains available, given the discontinued status of the original SN74LS595DG4.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS595D directly replace the SN74LS595DG4 in existing designs?

A: Yes. Both components share identical electrical parameters, functional specifications, and 16-SOIC package configuration. Pin-for-pin compatibility is maintained across all signal and power connections.

Q: What is the difference between the SN74LS595DG4 and SN74LS595D part numbers?

A: The suffix designations indicate different packaging formats. The DG4 suffix denotes a specific packaging variant, while the D suffix represents an alternative packaging configuration (Tube). The core silicon and electrical performance are equivalent.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components maintain identical ROHS3 compliance status, REACH unaffected classification, and Moisture Sensitivity Level 1 rating.

Q: What should be considered regarding product availability?

A: The SN74LS595DG4 is discontinued at DiGi Electronics. The SN74LS595D carries Last Time Buy status, indicating limited future production. Long-term design strategies should evaluate alternative shift register architectures if extended component availability is required.

Q: Are the operating conditions identical between these parts?

A: Yes. Both components operate across the same supply voltage range (4.75V ~ 5.25V) and temperature range (0°C ~ 70°C), with identical tri-state output configuration and serial-to-parallel functional capability.
