Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN7404NG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: Inverter (6 channels, 1 input per channel)
• Electrical Specifications: Supply voltage 4.75V ~ 5.25V, output current 400µA/16mA, input logic levels 0.8V/2V, propagation delay 22ns @ 5V with 15pF load
• Mechanical Compatibility: 14-DIP through-hole package with 0.300" (7.62mm) pitch
• Operating Temperature Range: 0°C ~ 70°C
• Compliance: ROHS3 Compliant, REACH Unaffected

The SN7404N qualifies as a direct substitute based on identical electrical and mechanical parameters. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The SN7404N is the recommended substitute for the discontinued SN7404NG4. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The SN7404N offers the advantage of active product status with higher inventory availability (4100 pcs vs. 1081 pcs). Both parts meet ROHS3 compliance and REACH requirements, ensuring regulatory compatibility in current manufacturing environments. The packaging format difference (tube vs. standard) does not affect functional performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can the SN7404N be used as a direct replacement for the SN7404NG4?

A: Yes. Both parts are identical in electrical performance and mechanical form factor. The SN7404N is the active equivalent with superior availability.

Q: Are there differences in the 14-DIP package between these parts?

A: No. Both use the standard 14-DIP (0.300", 7.62mm) through-hole package. Pin configuration and spacing are identical.

Q: Does the packaging format (tube vs. standard) affect circuit performance?

A: No. Packaging format affects only handling and storage logistics, not electrical or mechanical performance.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the SN7404NG4 and SN7404N are ROHS3 Compliant and REACH Unaffected.

Q: What is the operating temperature range for these inverter ICs?

A: Both parts operate across 0°C to 70°C, suitable for commercial and industrial applications within this thermal envelope.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical supply voltage (4.75V ~ 5.25V), logic levels, propagation delay, and output current specifications ensure direct functional equivalence in circuit designs.
