74HCT00D,652 NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74HCT00D,652 is a NAND Gate IC with 4 channels and 2 inputs per channel, manufactured by Nexperia USA Inc. in a 14-SO surface mount package. This part is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and procurement.

The 74HCT00 series represents a standard logic gate family with consistent functional performance across multiple manufacturers and packaging variants. Substitute parts maintain the same logic function, pin configuration, and electrical operating parameters within defined tolerances.

Primary Substitution Criteria:

Logic function: 4-channel NAND gate with 2 inputs per channel
Supply voltage range: 4.5V to 5.5V
Package footprint: 14-SOIC surface mount
Pin configuration: Identical pinout across all substitutes

Secondary Compatibility Factors:

Quiescent current specifications (40 µA for Nexperia; 2 µA for Texas Instruments and Harris variants)
Propagation delay characteristics (12ns to 20ns depending on manufacturer)
Operating temperature range (-40°C to 125°C for Nexperia; -40°C to 85°C for some Texas Instruments variants; -55°C to 125°C for Harris)
Product status and availability (Active, Last Time Buy, Discontinued, or Obsolete)
Compliance certifications (RoHS3, REACH status)

Substitutes are grouped into two categories: direct packaging equivalents and parametric equivalents with acceptable performance variations.

Engineering Selection Recommendations

Tier 1 - Direct Replacement (Recommended):

74HCT00D,653 (Nexperia USA Inc., Active): Identical electrical specifications and operating parameters to the main part. Packaging differs only in format (Tape & Reel vs. Tube). RoHS3 compliant. Recommended for new procurement.

Tier 2 - Functional Equivalent with Extended Temperature Range:

CD74HCT00M96 (Texas Instruments, Active): Maintains identical logic function and supply voltage range. Lower quiescent current (2 µA vs. 40 µA) and extended operating temperature range (-55°C to 125°C). Slightly higher propagation delay (20ns vs. 12ns). RoHS3 compliant. Suitable for applications requiring lower power consumption or extended temperature operation.

Tier 3 - Active Alternatives with Reduced Temperature Range:

SN74HCT00DR (Texas Instruments, Active): Active product status with standard packaging. Operating temperature limited to -40°C to 85°C. Propagation delay 18ns @ 5.5V. RoHS3 compliant. Acceptable for applications within the reduced temperature specification.
SN74HCT00NSR (Texas Instruments, Active): Active product with 14-SO package (0.209", 5.30mm width). Identical electrical performance to SN74HCT00DR. Verify package footprint compatibility before selection.

Tier 4 - Last Time Buy / Discontinued Status:

CD74HCT00MT (Texas Instruments, Last Time Buy): Active procurement window closing. Equivalent performance to CD74HCT00M96. Suitable only if immediate procurement is possible.
SN74HCT00D, SN74HCT00DG4, SN74HCT00DT (Texas Instruments, Discontinued at DiGi Electronics): No longer actively distributed. Use only if existing inventory is available through alternative channels.

Tier 5 - Obsolete or Non-Compliant:

CD74HCT00M (Harris Corporation, Obsolete): RoHS non-compliant. Not recommended for new designs.
74HCT00D/C152 (Nexperia USA Inc., Obsolete): Original part status. Replacement required.

Frequently Asked Questions (FAQ)

Q: Can I use SN74HCT00DR as a direct replacement for 74HCT00D,652?

A: Yes, with temperature range consideration. SN74HCT00DR maintains identical logic function, pin configuration, and supply voltage range. The operating temperature range is reduced from -40°C to 125°C to -40°C to 85°C. If your application operates within -40°C to 85°C, this part is functionally compatible. Verify propagation delay requirements; SN74HCT00DR specifies 18ns @ 5.5V versus 12ns @ 4.5V for the original part.

Q: What is the difference between 74HCT00D,652 and 74HCT00D,653?

A: Both parts are manufactured by Nexperia USA Inc. with identical electrical specifications. The primary difference is packaging format: 74HCT00D,652 is supplied in Tube packaging, while 74HCT00D,653 is supplied in Tape & Reel (TR) format. The 74HCT00D,653 is currently Active, making it the preferred choice for new procurement.

Q: Why do some substitutes have lower quiescent current (2 µA vs. 40 µA)?

A: Quiescent current variation reflects manufacturing process differences between Nexperia and Texas Instruments. Both values are within acceptable operating parameters for the 74HCT logic family. Lower quiescent current reduces power consumption in standby conditions. This difference does not affect functional compatibility.

Q: Is CD74HCT00M96 suitable for applications requiring the full -40°C to 125°C temperature range?

A: CD74HCT00M96 supports -55°C to 125°C operation, which exceeds the original part's -40°C to 125°C range. This part is suitable for applications requiring extended low-temperature operation beyond -40°C.

Q: What packaging considerations apply when selecting a substitute?

A: All listed substitutes use 14-SOIC surface mount packages with identical pinout. Physical package dimensions vary: most use 0.154" width (3.90mm), while SN74HCT00NSR uses 0.209" width (5.30mm). Verify PCB footprint compatibility before final selection. Packaging format (Tube, Tape & Reel, Cut Tape) affects procurement and handling but not electrical performance.

Q: Are all recommended substitutes RoHS3 compliant?

A: Most active substitutes are RoHS3 compliant. CD74HCT00M (Harris, Obsolete) is RoHS non-compliant. 74HCT00D/C118 (NXP) lists RoHS status as not applicable. Verify compliance documentation for your specific application requirements.

Q: Which substitute offers the best availability?

A: SN74HCT00DR and SN74HCT00NSR (Texas Instruments, Active status) and 74HCT00D,653 (Nexperia, Active status) represent the most readily available options with confirmed active product status and current manufacturing.
