Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74S04D is determined by strict equivalence across the following critical parameters:

• Logic function: 6-channel inverter with single input per channel
• Electrical specifications: 4.75V ~ 5.25V supply voltage, 5ns maximum propagation delay at 5V with 50pF load
• Input/output current ratings: 1mA output high, 20mA output low, 24mA maximum quiescent current
• Logic thresholds: 0.8V low input level, 2V high input level
• Package form factor: 14-SOIC surface mount configuration
• Environmental compliance: ROHS3 compliant, MSL Level 1

The SN74S04DR qualifies as a direct substitute based on identical electrical performance, logic configuration, and package specifications. The primary distinction is packaging format: SN74S04D is supplied in Tube packaging, while SN74S04DR is supplied in Tape & Reel format. Both devices share the same base product number (74S04) and maintain full functional and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SN74S04DR is the direct equivalent substitute for the SN74S04D. Both devices are manufactured by Texas Instruments and maintain identical electrical specifications, logic functionality, and package dimensions. The SN74S04DR carries Active product status with higher inventory availability (3034 pcs versus 1005 pcs), providing superior long-term supply security.

Selection between these parts should be based on procurement requirements: the SN74S04D in Tube packaging is suitable for lower-volume applications or existing stock utilization, while the SN74S04DR in Tape & Reel format is optimized for automated assembly processes and higher-volume production environments. Both devices satisfy ROHS3 compliance and REACH requirements without compromise.

Frequently Asked Questions (FAQ)

Q: Can the SN74S04DR directly replace the SN74S04D in existing designs?

A: Yes. The SN74S04DR is electrically and functionally identical to the SN74S04D. All electrical parameters, logic thresholds, propagation delays, and operating temperature ranges are equivalent. The 14-SOIC package dimensions are identical, enabling direct PCB footprint compatibility.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies individual components in a plastic tube, suitable for manual handling and lower-volume assembly. Tape & Reel packaging presents components on a continuous carrier tape wound on a reel, optimized for automated pick-and-place assembly equipment. Both formats contain the same component with identical specifications.

Q: Why is the SN74S04D marked as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued production of this part number. The SN74S04DR remains in Active production status, making it the recommended choice for new designs and ongoing procurement to ensure long-term availability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the SN74S04D and SN74S04DR maintain identical ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited) ratings. Environmental and regulatory certifications are equivalent.

Q: What is the maximum propagation delay specification?

A: Both devices specify a maximum propagation delay of 5 nanoseconds at 5V supply voltage with a 50pF load. This timing specification is identical across both part numbers.
