Engineering Selection Recommendations

SN74F04NSR (MFR Recommended Substitute): The SN74F04NSR is the manufacturer-recommended alternative to the obsolete SN74F04DRE4. This part maintains identical electrical specifications and operating parameters. The primary distinction is packaging format: the SN74F04NSR is supplied in Tape & Reel format with a slightly wider package body (5.30mm vs. 3.90mm). This part carries active product status, ensuring long-term availability and supply chain stability. Selection of this part is appropriate when Tape & Reel packaging is compatible with assembly processes.

SN74F04DR (Parametric Equivalent): The SN74F04DR provides parametric equivalence with identical electrical characteristics and the same 14-SOIC package dimensions as the original SN74F04DRE4 (0.154", 3.90mm width). This part is also active and ROHS3 compliant. The SN74F04DR is suitable for applications where package footprint compatibility with existing designs is a primary requirement. This part is supplied in Tape & Reel format.

Both substitute parts satisfy all electrical and compliance requirements for direct functional replacement of the obsolete SN74F04DRE4.

Frequently Asked Questions (FAQ)

Q: Can the SN74F04NSR be used as a direct replacement for the SN74F04DRE4?

A: Yes. The SN74F04NSR is electrically identical to the SN74F04DRE4 and maintains all specified logic levels, propagation delays, and operating parameters. The package width difference (5.30mm vs. 3.90mm) must be evaluated for PCB layout compatibility. Both parts are 14-SOIC surface mount packages with identical pin configurations.

Q: What is the difference between the SN74F04NSR and SN74F04DR?

A: Both parts are electrically equivalent to the SN74F04DRE4. The primary difference is package width: the SN74F04DR matches the original 3.90mm width, while the SN74F04NSR is 5.30mm wide. Selection depends on PCB layout constraints and assembly process requirements.

Q: Why is the SN74F04DRE4 listed as obsolete?

A: The SN74F04DRE4 has been discontinued by Texas Instruments. Active equivalent parts (SN74F04NSR and SN74F04DR) are available to support ongoing system requirements and new designs.

Q: Are all three parts ROHS3 compliant?

A: Yes. The SN74F04DRE4, SN74F04NSR, and SN74F04DR are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What packaging formats are available?

A: The SN74F04DRE4 is supplied in tube packaging. The SN74F04NSR and SN74F04DR are supplied in Tape & Reel format, which is standard for high-volume manufacturing and automated assembly processes.

Q: Do these parts have identical electrical performance?

A: Yes. All three parts share identical specifications for supply voltage (4.5V ~ 5.5V), output current (1mA, 20mA), input logic levels (0.8V low, 2V high), and propagation delay (5ns @ 5V, 50pF).
