74LVC00ADB,112 Equivalent & Substitute Parts

Part Overview

The 74LVC00ADB,112 is a NAND Gate IC with 4 channels and 2 inputs per channel, manufactured by Nexperia USA Inc. in a 14-SSOP package. This logic gate is classified as obsolete, which necessitates identifying functionally equivalent substitute parts for ongoing design support and procurement. The 74LVC series operates across a wide voltage range (1.2V to 3.6V) and is suitable for low-power digital logic applications requiring NAND gate functionality.

Output Drive Capability: 24mA high and low
Propagation Delay: 4.3ns or faster @ 3.3V, 50pF load
Operating Temperature: Minimum -40°C to 125°C support

Engineering Selection Recommendations

Primary Recommendation: 74LVC00APW,118 (Nexperia)

This part is the direct active equivalent to the obsolete 74LVC00ADB,112. It maintains identical electrical specifications, voltage range (1.2V–3.6V), quiescent current (40 µA), and propagation delay (4.3ns). The only difference is the package variant (14-TSSOP vs. 14-SSOP), which is mechanically compatible. This part is currently in active production status with 7030 units in stock.

Secondary Recommendation: SN74LVC00ADB or SN74LVC00APWT (Texas Instruments)

These Texas Instruments parts offer superior performance characteristics: lower quiescent current (1 µA vs. 40 µA) and faster propagation delay (4.1ns vs. 4.3ns). Both maintain the full -40°C to 125°C operating range and are RoHS3 compliant. SN74LVC00ADB preserves the 14-SSOP package, while SN74LVC00APWT uses 14-TSSOP. Both are in active production.

Alternative for Extended Temperature Range: SN74LVC00AMPWREP (Texas Instruments)

If extended low-temperature operation to -55°C is required, SN74LVC00AMPWREP provides this capability. Trade-offs include reduced voltage supply floor (2V minimum) and slightly higher quiescent current (10 µA).

Not Recommended: 74LCX00MTCX (onsemi)

While functionally equivalent, this part has a reduced operating temperature range (-40°C to 85°C maximum) compared to the original specification (-40°C to 125°C). Use only if application temperature limits do not exceed 85°C.

Avoid: SN74LVC00APWE4 and SN74LVC00APWRG4

Both parts are discontinued at DiGi Electronics and should not be selected for new designs despite active inventory.

Frequently Asked Questions (FAQ)

Q: Can I use a 14-TSSOP package substitute in place of the original 14-SSOP package?

A: Yes. Both packages are mechanically compatible for surface-mount PCB assembly. The 14-TSSOP (0.173" width) is slightly narrower than 14-SSOP (0.209" width), but pinout and electrical function are identical. Verify PCB footprint design accommodates the narrower package width.

Q: What is the difference between the Nexperia 74LVC00APW,118 and Texas Instruments SN74LVC00APW?

A: Both are 14-TSSOP NAND gate ICs with identical logic function. The Texas Instruments version offers lower quiescent current (1 µA vs. 40 µA) and faster propagation delay (4.1ns vs. 4.3ns). The Nexperia part supports a lower voltage floor (1.2V vs. 1.65V). Select based on power consumption and speed requirements.

Q: Is the onsemi 74LCX00MTCX a suitable replacement?

A: The 74LCX00MTCX is functionally equivalent but has a reduced maximum operating temperature of 85°C versus the original 125°C. It is suitable only for applications with temperature limits not exceeding 85°C. Additionally, the minimum supply voltage is 2V rather than 1.2V.

Q: Why does the Texas Instruments SN74LVC00ADB have lower quiescent current than the original part?

A: This reflects manufacturing process improvements and design optimization by Texas Instruments. The lower quiescent current (1 µA vs. 40 µA) is a performance advantage for battery-powered or low-power applications and does not affect functional compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and have Moisture Sensitivity Level 1 (unlimited shelf life), matching the original part's compliance status.

Q: What packaging options are available for the 74LVC00 logic gate?

A: The 74LVC00 base product is available in two surface-mount packages: 14-SSOP (0.209" width) and 14-TSSOP (0.173" width). Both packages contain identical pinouts and electrical specifications. Selection depends on PCB layout constraints and assembly equipment capabilities.

Q: Can I substitute the 74LVC00ADB,112 with SN74LVC00AQPWREP?

A: Yes, with voltage supply considerations. The SN74LVC00AQPWREP operates from 2V to 3.6V (vs. 1.2V to 3.6V for the original). If your application requires operation below 2V, this part is not suitable. For standard 3.3V and 5V logic systems, it is fully compatible.
