SN74HC32NS Equivalent & Substitute Parts

Part Overview

The SN74HC32NS is a 4-channel 2-input OR gate logic IC manufactured by Texas Instruments in a 14-SO surface mount package. This component is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design requirements and production needs. The SN74HC32NS remains functionally available through alternative packaging and sourcing options that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74HC32NS is determined by the following critical parameters:

• Logic function: 4-channel 2-input OR gate configuration
• Package type: 14-SOIC surface mount form factor
• Electrical specifications: Supply voltage range 2V ~ 6V, propagation delay 17ns @ 6V with 50pF load, output current capability 5.2mA
• Compliance: ROHS3 compliance and MSL Level 1 rating
• Series compatibility: 74HC logic family

The SN74HC32NSR qualifies as a direct substitute based on identical logic configuration, package dimensions, electrical performance characteristics, and compliance certifications. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tube) and product status (Active versus Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The SN74HC32NSR is a direct functional and mechanical equivalent to the SN74HC32NS. Both components share identical electrical specifications, package dimensions, and compliance certifications. The SN74HC32NSR is the recommended selection for new designs and production requirements due to its active product status and continued availability. The substitution is valid for all applications where the SN74HC32NS was previously specified, with no circuit modifications required. Packaging format differences (Tube versus Cut Tape & Digi-Reel) affect procurement and handling procedures but do not impact electrical performance or board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC32NSR be used as a direct replacement for the SN74HC32NS?

A: Yes. Both parts are identical in logic function, electrical performance, and 14-SOIC package dimensions. No circuit redesign is necessary.

Q: What is the difference between the Tube and Cut Tape packaging formats?

A: Tube packaging supplies components in plastic tubes for manual handling and small-quantity applications. Cut Tape & Digi-Reel packaging provides components on continuous tape for automated pick-and-place assembly. Both formats contain the same component with identical specifications.

Q: Are there any input logic level differences between these parts?

A: Input logic level specifications differ slightly between the two parts. The SN74HC32NS specifies 0.1V ~ 0.26V for low and 1.998V ~ 5.8V for high. The SN74HC32NSR specifies 0.5V ~ 1.8V for low and 1.5V ~ 4.2V for high. Both operate within the standard 74HC logic family input thresholds and are compatible in typical applications.

Q: Do both parts meet RoHS and REACH compliance requirements?

A: Yes. Both the SN74HC32NS and SN74HC32NSR are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these components?

A: Both parts have MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
