Key Parameters

Substitute Part Grouping Explanation

Substitution of the N74F07D,623 is determined by the following critical parameters:

• Logic Function: Non-inverting buffer with 6 elements, 1 bit per element
• Package Compatibility: 14-SOIC form factor (0.154", 3.90mm width)
• Supply Voltage Range: 4.5V ~ 5.5V operation
• Operating Temperature: 0°C ~ 70°C
• Output Configuration: Logic output capability (note: original part features open collector; substitute provides logic output)
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The SN74AS1034ADR from Texas Instruments satisfies the functional and physical requirements for substitution, with the distinction that it provides logic output rather than open collector output. This represents a functional upgrade in output capability while maintaining electrical compatibility within the specified voltage and temperature parameters.

Parameter Comparison

Engineering Selection Recommendations

The SN74AS1034ADR is the designated substitute for the obsolete N74F07D,623. Both components maintain identical supply voltage specifications (4.5V ~ 5.5V), operating temperature range (0°C ~ 70°C), and physical package dimensions (14-SOIC). Both parts achieve ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

The primary distinction between these parts is the output configuration: the original N74F07D,623 provides open collector output, while the SN74AS1034ADR provides logic output. This change represents a functional enhancement that expands application flexibility. The SN74AS1034ADR is currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the SN74AS1034ADR directly replace the N74F07D,623 in existing designs?

A: The SN74AS1034ADR is functionally compatible in terms of logic operation, supply voltage, temperature range, and package form factor. The output type difference (logic output versus open collector) must be evaluated within the context of the specific circuit application to ensure compatibility with downstream components.

Q: Are there any electrical parameter differences that affect circuit operation?

A: The output current specifications differ between the parts. The N74F07D,623 specifies 64mA low output current, while the SN74AS1034ADR specifies 48mA for both high and low output. Circuit designs must account for these current ratings when determining load compatibility.

Q: What is the significance of the product status difference?

A: The N74F07D,623 is classified as obsolete, indicating discontinued manufacturing and limited availability. The SN74AS1034ADR maintains active production status, ensuring reliable sourcing for new designs and ongoing system support.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Both the N74F07D,623 and SN74AS1034ADR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Does the 14-SOIC package ensure mechanical compatibility?

A: Both parts utilize the 14-SOIC package with identical dimensions (0.154", 3.90mm width), ensuring mechanical compatibility for PCB assembly and socket-based applications.
