Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

74HC08D,653 from Nexperia USA Inc. is the direct successor to the obsolete 74HC08D,652. Both parts share identical electrical specifications and are from the same manufacturer. The 74HC08D,653 is actively produced and available in higher quantities, making it the preferred choice for design continuity.

CD74HC08QM96Q1 from Texas Instruments is an active automotive-grade part (AEC-Q100 qualified) with identical electrical performance. This variant is suitable for applications requiring automotive qualification or extended reliability documentation.

MC74HC08ADR2G from onsemi offers improved performance characteristics: lower quiescent current (1 µA vs. 2 µA) and faster propagation delay (13 ns vs. 15 ns). This part is actively produced and RoHS3 compliant, making it suitable for power-sensitive or timing-critical applications.

Extended Temperature Range Options:

CD74HC08M96 and MC74HC08ADG both support -55°C to 125°C operating temperature, compared to the original -40°C to 125°C range. These parts are appropriate for industrial or military-grade applications requiring wider temperature margins.

Parts to Avoid:

CD74HC08M (Harris Corporation) is obsolete and RoHS non-compliant. MM74HC08M and MM74HC08MX from Fairchild Semiconductor have slower propagation delay (20 ns) and narrower operating temperature range (-40°C to 85°C), making them unsuitable as direct replacements for the original specification.

Frequently Asked Questions (FAQ)

Q: Can I use 74HC08D,653 as a direct replacement for 74HC08D,652?

A: Yes. Both parts are manufactured by Nexperia USA Inc. and share identical electrical specifications, pin configuration, and package dimensions. The 74HC08D,653 is the active production variant of the same product line.

Q: What is the difference between the Texas Instruments CD74HC08QM96EP and CD74HC08QM96Q1 variants?

A: Both parts have identical electrical specifications. The CD74HC08QM96Q1 carries AEC-Q100 automotive qualification, making it suitable for automotive applications. The CD74HC08QM96EP is the standard industrial variant.

Q: Why do some substitutes show faster propagation delay (13 ns vs. 15 ns)?

A: The onsemi MC74HC08ADR2G and MC74HC08ADG parts demonstrate faster propagation delay within the same 14-SOIC package. This represents improved silicon performance and is fully compatible with designs expecting 15 ns or slower timing. Faster propagation delay does not create compatibility issues in standard logic applications.

Q: Are all listed substitutes RoHS3 compliant?

A: Most active production parts are RoHS3 compliant. The CD74HC08M from Harris Corporation is RoHS non-compliant and obsolete. The MM74HC08M and MM74HC08MX from Fairchild Semiconductor do not specify RoHS status. For new designs, select parts explicitly marked ROHS3 Compliant.

Q: What packaging options are available?

A: Substitutes are available in Cut Tape & Digi-Reel, Tape & Reel, and Tube packaging. All maintain the 14-SOIC (0.154", 3.90mm width) case dimension. Packaging selection depends on procurement volume and assembly process requirements.

Q: Can I use MM74HC08M or MM74HC08MX as substitutes?

A: These parts are electrically compatible but have slower propagation delay (20 ns vs. 15 ns) and narrower operating temperature range (-40°C to 85°C vs. -40°C to 125°C). Use only if your application tolerates these performance reductions.
