Engineering Selection Recommendations

SN74LVC08APWR (Texas Instruments) is the primary substitute for the 74LVC08AT14-13. This part maintains identical supply voltage range (1.65V ~ 3.6V overlap), matching input logic levels, and equivalent propagation delay (3.9ns). The quiescent current specification of 1 µA is superior to the main part. All compliance certifications align, and the part is active with extensive inventory availability (197,968 pcs).

74LVC08APW,118 (Nexperia USA Inc.) is a secondary substitute with functional equivalence and identical package compatibility. The supply voltage range (1.2V ~ 3.6V) provides lower minimum voltage operation but reduces the upper limit to 3.6V compared to the main part's 5.5V maximum. The quiescent current specification (40 µA) is higher than the main part. Propagation delay (4.1ns) is marginally higher. This part is suitable for applications operating within the 1.2V to 3.6V range where the main part's extended voltage capability is not required.

All substitute parts maintain active product status, RoHS3 compliance, and REACH unaffected designation, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC08APW,118 replace the 74LVC08AT14-13 in all applications?

A: The 74LVC08APW,118 is functionally equivalent but has a reduced maximum supply voltage of 3.6V compared to the main part's 5.5V. It is suitable only for applications operating within the 1.2V to 3.6V range. If your circuit requires operation above 3.6V, use the SN74LVC08APWR instead.

Q: What is the significance of the different quiescent current specifications?

A: Quiescent current represents power consumption when the device is not actively switching. The SN74LVC08APWR (1 µA) consumes less standby power than the 74LVC08AT14-13 (10 µA), making it preferable for battery-powered or low-power applications. The 74LVC08APW,118 (40 µA) consumes more standby power and is less suitable for power-sensitive designs.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 14-TSSOP package with identical physical dimensions (0.173", 4.40mm Width) and the same pin configuration for 4-channel AND gate logic. No PCB layout modifications are required for substitution.

Q: What is the difference in propagation delay between these parts?

A: At 3.3V supply with 50pF load, the 74LVC08AT14-13 and SN74LVC08APWR both specify 3.9ns propagation delay. The 74LVC08APW,118 specifies 4.1ns, a 0.2ns difference. For most general-purpose logic applications, this difference is negligible. High-speed timing-critical designs should verify this specification against system requirements.

Q: Which substitute part has the best overall performance?

A: The SN74LVC08APWR offers the best combination of specifications: it maintains the full supply voltage range of the main part (1.65V ~ 3.6V overlap), has the lowest quiescent current (1 µA), and matches the propagation delay (3.9ns). It is the recommended primary substitute.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts—74LVC08AT14-13, 74LVC08APW,118, and SN74LVC08APWR—are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
