Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LS465DW is determined by the following critical parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Voltage - Supply: 4.75V ~ 5.25V
• Operating Temperature: 0°C ~ 70°C (TA)
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

The SN74LS541DWR qualifies as a direct substitute based on matching all critical functional and physical parameters. Both devices share identical logic architecture, pin configuration, supply voltage specifications, operating temperature range, and package form factor.

Parameter Comparison

Engineering Selection Recommendations

The SN74LS541DWR is a qualified substitute for the SN74LS465DW based on functional equivalence across all critical parameters. The SN74LS541DWR carries Active product status, ensuring ongoing availability and manufacturing support from Texas Instruments, whereas the SN74LS465DW is Obsolete.

Both parts maintain ROHS3 compliance and identical supply voltage and operating temperature specifications. The SN74LS541DWR demonstrates higher output high current capability (15mA versus 2.6mA), which represents an enhancement in drive capability without introducing incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS541DWR directly replace the SN74LS465DW in existing designs?

A: Yes. Both devices share identical logic type, element count, bit configuration, output type, supply voltage range, operating temperature range, and 20-SOIC package form factor. Pin-to-pin compatibility is maintained.

Q: What is the significance of the difference in output high current specifications?

A: The SN74LS541DWR provides 15mA output high current compared to the SN74LS465DW's 2.6mA. This represents increased drive capability and does not create compatibility issues in applications designed for the original part.

Q: Why is product status relevant to substitution?

A: The SN74LS465DW is Obsolete, meaning Texas Instruments no longer manufactures this device. The SN74LS541DWR carries Active status, ensuring continued production, availability, and technical support.

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

A: Both parts are ROHS3 compliant and carry identical REACH and ECCN classifications. No compliance barriers exist to substitution.

Q: Does the packaging format differ between these parts?

A: Both parts use the 20-SOIC (0.295", 7.50mm Width) surface mount package. Physical dimensions and pin spacing are identical.
