Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 74F541PC is determined by strict alignment of the following electrical and mechanical parameters:

• Logic Function: Buffer, Non-Inverting with identical element and bit configuration (1 element, 8 bits per element)
• Output Configuration: 3-State output capability
• Supply Voltage Range: 4.5V ~ 5.5V operation
• Operating Temperature Range: 0°C ~ 70°C (TA)
• Package Type: 20-DIP (0.300", 7.62mm) with Through Hole mounting
• Pin Configuration: Identical 20-PDIP supplier device package

The SN74F541N from Texas Instruments meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The SN74F541N is a direct functional substitute for the 74F541PC. Both components share identical logic architecture, pin configuration, and core electrical specifications within the defined operating parameters. The SN74F541N offers the advantage of active product status from Texas Instruments, ensuring continued availability and supply chain reliability. The SN74F541N is RoHS3 compliant, meeting current environmental and regulatory standards. Output current specifications differ slightly (15mA vs. 3mA for high output), which remains within acceptable tolerance for standard TTL logic applications operating at the specified voltage and temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the SN74F541N directly replace the 74F541PC in existing designs?

A: Yes. Both components are 20-DIP through-hole packages with identical pin assignments, logic function, and core electrical specifications. Direct socket substitution is supported.

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

A: The SN74F541N provides 15mA output high current compared to the 74F541PC's 3mA. This represents improved drive capability and does not create compatibility issues in standard TTL logic applications. The output low current specification of 64mA is identical across both parts.

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

A: The SN74F541N is RoHS3 compliant and carries active product status. The 74F541PC is classified as obsolete. Both share identical REACH and ECCN classifications (REACH Unaffected, EAR99).

Q: What packaging options are available for the SN74F541N?

A: The SN74F541N is supplied in Tube packaging, whereas the 74F541PC inventory information does not specify packaging format. Both maintain the 20-PDIP physical package specification.

Q: Are the operating temperature ranges identical?

A: Yes. Both the 74F541PC and SN74F541N operate across 0°C to 70°C (TA), ensuring compatibility in equivalent thermal environments.
