Substitute Part Grouping Explanation

Substitute parts for the SN74LS465NG4 are identified based on the following critical parameters that determine functional and physical compatibility:

• 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-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

The SN74LS541N qualifies as a direct substitute based on matching all core functional and physical parameters within the 74LS logic family.

Parameter Comparison

Engineering Selection Recommendations

The SN74LS541N is the qualified substitute for the obsolete SN74LS465NG4. Both components maintain identical functional specifications for 8-bit non-inverting buffering with 3-State output capability and are housed in the same 20-DIP through-hole package.

The SN74LS541N carries Active product status, ensuring ongoing availability and manufacturing support from Texas Instruments. Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying current environmental and regulatory requirements.

The output current specification for the high state differs between the two parts (2.6mA versus 15mA), with the SN74LS541N providing higher output drive capability. This difference does not prevent substitution in applications designed for the SN74LS465NG4, as the substitute meets or exceeds the original specification.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS541N directly replace the SN74LS465NG4 in existing designs?

A: Yes. Both components share identical logic type, element count, bit width, output type, supply voltage range, operating temperature range, and 20-DIP package configuration. Direct pin-for-pin substitution is supported.

Q: What is the significance of the different output current ratings?

A: The SN74LS541N provides 15mA output high current compared to the SN74LS465NG4's 2.6mA. This represents improved drive capability in the substitute part. Applications designed for the original part will function with the substitute, as the substitute meets or exceeds the original specification.

Q: Why is the SN74LS465NG4 marked as Obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued manufacturing of this part number. The SN74LS541N is the active equivalent that provides the same functional performance and package configuration.

Q: Are there any compliance differences between these parts?

A: Both parts maintain ROHS3 compliance and REACH Unaffected status. No compliance barriers exist to substitution.

Q: Does the through-hole 20-DIP package remain the same for both parts?

A: Yes. Both the SN74LS465NG4 and SN74LS541N use the 20-DIP (0.300", 7.62mm) through-hole package, ensuring mechanical and electrical compatibility on existing PCB layouts.
