SN74LVC00APWRE4 Equivalent & Substitute Parts

Part Overview

The SN74LVC00APWRE4 is a NAND Gate IC with 4 channels and 2 inputs per channel, manufactured by Texas Instruments in a 14-TSSOP surface mount package. This part operates across a supply voltage range of 1.65V to 3.6V with low quiescent current of 1 µA maximum and propagation delay of 4.1ns at 3.3V with 50pF load. The product is currently discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the SN74LVC00APWRE4 is determined by the following critical parameters: logic type (NAND Gate), circuit count (4 channels), input count (2 inputs per channel), package type (14-TSSOP), and mounting method (surface mount). All substitute parts must maintain these core functional and physical characteristics.

The substitute parts are grouped into two categories based on parametric equivalence:

Parametric Equivalents (Texas Instruments 74LVC Series): Parts that match all electrical specifications including supply voltage range (1.65V ~ 3.6V), quiescent current (1 µA max), and propagation delay (4.1ns @ 3.3V, 50pF). These include SN74LVC00APWRG4 and SN74LVC00APWT, differing only in packaging format (Tape & Reel vs. standard).

Manufacturer Recommended Alternatives: Parts from onsemi (74LCX series) and Nexperia (74LVC series) that maintain the same logic function, circuit topology, and package but with variations in supply voltage range, quiescent current, propagation delay, and operating temperature. These alternatives are suitable where the specific electrical parameter variations are acceptable for the application.

Engineering Selection Recommendations

For direct replacement of the discontinued SN74LVC00APWRE4, the SN74LVC00APWT from Texas Instruments is the primary choice. This part maintains identical electrical specifications and operating temperature range while offering active product status and established supply availability.

The SN74LVC00APWRG4 provides parametric equivalence with identical electrical performance but differs in packaging format (Tape & Reel). Selection between these two Texas Instruments options depends on procurement and assembly requirements.

For applications where the lower supply voltage limit of 1.65V is not required, the onsemi 74LCX series (74LCX00MTCX, MC74LCX00DTG, MC74LCX00DTR2G) and Nexperia 74LVC00APW,118 are viable alternatives. These parts maintain the same logic function and package but operate with higher quiescent current and longer propagation delays. The onsemi parts are limited to -40°C to 85°C operating temperature, which excludes applications requiring the full -40°C to 125°C range of the original part.

All substitute parts are ROHS3 compliant and carry equivalent regulatory certifications (REACH Unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can I use the 74LCX00MTCX as a direct replacement for the SN74LVC00APWRE4?

A: The 74LCX00MTCX is functionally compatible in the same 14-TSSOP package with identical logic operation. However, it differs in three key parameters: minimum supply voltage (2V vs. 1.65V), quiescent current (10 µA vs. 1 µA), and maximum operating temperature (85°C vs. 125°C). Use this part only if your application does not require operation below 2V supply voltage or above 85°C ambient temperature.

Q: What is the difference between SN74LVC00APWRG4 and SN74LVC00APWT?

A: Both parts are Texas Instruments 74LVC series with identical electrical specifications and operating temperature range. The difference is packaging format: SN74LVC00APWRG4 is supplied in Tape & Reel format while SN74LVC00APWT is also in Tape & Reel. Both are parametric equivalents suitable for direct substitution based on procurement preference.

Q: Why does the Nexperia 74LVC00APW,118 have a wider supply voltage range (1.2V ~ 3.6V)?

A: The Nexperia part extends the lower supply voltage limit to 1.2V, which may be beneficial for ultra-low-power applications. However, this comes with trade-offs: quiescent current increases to 40 µA (vs. 1 µA for the original part) and input logic level thresholds shift (0.12V ~ 0.8V for low vs. 0.7V ~ 0.8V). Verify compatibility with your specific circuit design before selection.

Q: Are all substitute parts available in the same 14-TSSOP package?

A: Yes, all listed substitute parts use the 14-TSSOP (0.173", 4.40mm Width) package, ensuring mechanical and electrical pin compatibility. Packaging format (Tape & Reel, Cut Tape, or Tube) varies by part number but does not affect circuit board assembly compatibility.

Q: Which substitute part has the fastest propagation delay?

A: The SN74LVC00APWRE4, SN74LVC00APWRG4, and SN74LVC00APWT all share the fastest propagation delay of 4.1ns at 3.3V with 50pF load. The onsemi 74LCX series parts have propagation delays of 5.2ns to 5.5ns, which may impact timing-critical applications.
