SN74LS07NS Equivalent & Substitute Parts

Part Overview

The SN74LS07NS is a Buffer, Non-Inverting logic integrated circuit manufactured by Texas Instruments, featuring 6 elements with 1 bit per element and open collector output configuration. This component operates within the 4.75V to 5.25V supply voltage range and is rated for 0°C to 70°C operating temperature. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain identical electrical and mechanical specifications for seamless circuit integration.

Substitute Part Grouping Explanation

Substitution of the SN74LS07NS is determined by strict equivalence across the following critical parameters:

• Logic Type: Buffer, Non-Inverting configuration
• Element Count: 6 elements with 1 bit per element
• Output Configuration: Open Collector output
• Output Current Rating: 40mA maximum low output current
• Supply Voltage Range: 4.75V to 5.25V
• Operating Temperature Range: 0°C to 70°C
• Package Type: 14-SOIC surface mount package
• Pin Compatibility: Identical 14-pin SOIC footprint

The SN74LS07NSR qualifies as a direct substitute based on complete alignment with all electrical specifications and mechanical packaging requirements. The primary distinction between these parts is packaging format and product availability status.

Parameter Comparison

Engineering Selection Recommendations

The SN74LS07NSR is the direct equivalent substitute for the discontinued SN74LS07NS. Both parts are manufactured by Texas Instruments and maintain identical electrical characteristics, pin configuration, and mechanical package specifications. The SN74LS07NSR carries Active product status with significantly higher inventory availability (50,400 pieces in stock versus 1,142 pieces for the original part). Both components satisfy ROHS3 compliance and REACH unaffected status requirements. The substitution involves no functional or performance trade-offs; the difference is limited to packaging format (Cut Tape/Digi-Reel versus Tube) and product lifecycle status. For new designs or component replenishment, the SN74LS07NSR is the appropriate selection due to active manufacturing status and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS07NSR be used as a direct replacement for the SN74LS07NS in existing circuits?

A: Yes. The SN74LS07NSR is electrically and mechanically identical to the SN74LS07NS. All pin assignments, voltage ratings, current specifications, and operating temperature ranges are equivalent. No circuit modifications are required.

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

A: Tube packaging contains components in a plastic tube suitable for manual handling and small-quantity applications. Cut Tape and Digi-Reel packaging are designed for automated assembly processes and higher-volume production. The internal component specifications remain identical.

Q: Are there any compliance differences between these parts?

A: No. Both the SN74LS07NS and SN74LS07NSR are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). Compliance certifications are equivalent.

Q: Why is the SN74LS07NS discontinued?

A: Product discontinuation is a lifecycle decision by the manufacturer. The SN74LS07NSR remains in active production and serves the same functional purpose, making it the recommended alternative for ongoing supply requirements.

Q: Will the 14-SOIC package footprint remain the same for the substitute part?

A: Yes. Both parts use the 14-SOIC package with identical dimensions (0.209" width, 5.30mm). PCB layouts and footprints require no modification.

Q: What is the maximum output current specification for these buffer ICs?

A: The maximum low output current is 40mA. High output current is not specified (indicated by "-" in the datasheet parameters), which is typical for open collector output configurations.
