74F32PC OR Gate IC Equivalent & Substitute Parts

Part Overview

The 74F32PC is a 4-channel 2-input OR gate logic IC manufactured by onsemi in 14-MDIP packaging. This component implements four independent OR logic functions, each with two inputs, operating at standard TTL voltage levels (4.5V to 5.5V). The part is classified as obsolete, making identification of active equivalent alternatives essential for design continuity and procurement planning.

Substitute Part Grouping Explanation

Substitution for the 74F32PC is determined by strict equivalence across the following critical parameters:

• Logic function: 4-channel 2-input OR gate
• Supply voltage range: 4.5V ~ 5.5V
• Output current specifications: 1mA (high), 20mA (low)
• Input logic thresholds: 0.8V (low), 2V (high)
• Propagation delay: 5.6ns @ 5V, 50pF
• Operating temperature range: 0°C ~ 70°C
• Package type: 14-DIP through-hole configuration
• Series classification: 74F

The identified substitutes (SN74F32N and SN74F32NE4) maintain full parametric equivalence across all specified electrical and mechanical characteristics. Both are manufactured by Texas Instruments and carry active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

Both SN74F32N and SN74F32NE4 are direct functional replacements for the obsolete 74F32PC. Selection between the two Texas Instruments alternatives should be based on the following factors:

SN74F32N is the standard active production variant, suitable for general applications requiring 74F32 OR gate functionality with confirmed propagation delay specifications at 50pF load conditions.

SN74F32NE4 provides identical electrical performance with explicit quiescent current specification (15.5 mA maximum) and is packaged in tube format. This variant is appropriate for applications where quiescent current monitoring is a design requirement.

Both substitutes carry ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements. The 14-DIP through-hole package remains consistent across all three parts, enabling direct socket compatibility in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can SN74F32N and SN74F32NE4 be used interchangeably with 74F32PC?

A: Yes. Both Texas Instruments parts maintain full parametric equivalence with the onsemi 74F32PC across all specified electrical characteristics, logic function, and package dimensions. Direct substitution is supported without circuit modification.

Q: What is the difference between SN74F32N and SN74F32NE4?

A: Both parts are electrically equivalent 74F32 OR gate ICs. SN74F32NE4 includes explicit quiescent current specification (15.5 mA maximum), while SN74F32N does not document this parameter. Packaging format differs (tube vs. standard), but electrical performance and pin configuration are identical.

Q: Are the substitute parts compatible with the original 14-DIP package footprint?

A: Yes. All three parts use the 14-DIP (0.300", 7.62mm) through-hole package configuration, ensuring mechanical and electrical compatibility with existing PCB designs without layout modifications.

Q: Why is the 74F32PC listed as obsolete?

A: The 74F32PC is an onsemi product that has reached end-of-life status. Active alternatives from Texas Instruments (SN74F32N and SN74F32NE4) provide continued access to 74F32 OR gate functionality with full parametric equivalence.

Q: Do the substitute parts meet current regulatory standards?

A: Yes. Both SN74F32N and SN74F32NE4 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
