Engineering Selection Recommendations

Primary Substitutes (Active Status, ROHS3 Compliant):

SN74HCT00DR and SN74HCT00NSR are direct functional equivalents from Texas Instruments with active product status and full RoHS3 compliance. SN74HCT00DR operates to -40°C to 85°C and offers improved propagation delay performance (18ns). SN74HCT00NSR provides identical electrical performance with a wider package body (0.209" versus 0.154"), which may affect PCB layout compatibility.

74HCT00D-Q100,118 from Nexperia USA Inc. is qualified to AEC-Q100 automotive standards and maintains the full -40°C to 125°C temperature range of the primary part. This part exhibits superior propagation delay (12ns) and is suitable for applications requiring automotive-grade components.

CD74HCT00M96 from Texas Instruments extends the operating temperature range to -55°C to 125°C while maintaining active product status and ROHS3 compliance. This part is appropriate for extended temperature applications.

Secondary Substitutes (Limited Availability):

CD74HCT00MT carries Last Time Buy status and should be considered only when primary alternatives are exhausted. SN74HCT00D, SN74HCT00DG4, and SN74HCT00DT are discontinued at DiGi Electronics and represent legacy inventory only.

Not Recommended:

CD74HCT00M from Harris Corporation is obsolete and non-RoHS3 compliant. This part should not be selected for new designs.

Frequently Asked Questions (FAQ)

Q: Can I substitute SN74HCT00DR for 74HCT00S14-13 in my design?

A: Yes. SN74HCT00DR is functionally equivalent with identical logic configuration (4 NAND gates, 2 inputs each), matching supply voltage range (4.5V ~ 5.5V), and identical output drive capability (4mA). The operating temperature range is narrower (-40°C to 85°C versus -125°C), so verify your application does not require the extended upper temperature limit of the primary part.

Q: What is the difference between the 14-SOIC (0.154") and 14-SOIC (0.209") packages?

A: Both are 14-pin SOIC packages with identical pin pitch and electrical compatibility. The difference is body width: 0.154" (3.90mm) versus 0.209" (5.30mm). The wider package (SN74HCT00NSR) may not fit in PCB layouts designed for the narrower variant. Verify PCB footprint compatibility before substitution.

Q: Is 74HCT00D-Q100,118 suitable for automotive applications?

A: Yes. This part carries AEC-Q100 qualification, indicating it meets automotive industry reliability and quality standards. It maintains the full -40°C to 125°C operating range and offers superior propagation delay performance (12ns).

Q: Why do some substitutes have lower quiescent current than the primary part?

A: Quiescent current variation (2 µA to 40 µA) reflects manufacturing process differences between suppliers while maintaining functional equivalence. Lower quiescent current reduces standby power consumption and is generally advantageous. Higher quiescent current (40 µA in 74HCT00D-Q100,118) remains within acceptable limits for most applications.

Q: Can I use CD74HCT00M for new designs?

A: No. This part is obsolete and non-RoHS3 compliant. It should not be selected for new designs. Use active, RoHS3-compliant alternatives such as SN74HCT00DR, CD74HCT00M96, or 74HCT00D-Q100,118.

Q: What does "Last Time Buy" status mean for CD74HCT00MT?

A: Last Time Buy indicates the manufacturer has announced end-of-life for this part. Existing inventory may be available, but no future production is planned. This part should be considered only as a temporary solution when primary alternatives are unavailable.
