SN74LVC04APWG4 Equivalent & Substitute Parts

Part Overview

The SN74LVC04APWG4 is a 6-channel inverter logic IC manufactured by Texas Instruments in 14-TSSOP surface mount packaging. This part is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and procurement. The SN74LVC04APWG4 operates across a 1.65V to 3.6V supply voltage range with low quiescent current and fast propagation delay characteristics suitable for general-purpose logic inversion applications.

Substitute Part Grouping Explanation

Substitution for the SN74LVC04APWG4 is determined by the following critical parameters:

Logic Function: 6-channel inverter with single input per channel
Package Type: 14-TSSOP surface mount form factor
Supply Voltage Range: Minimum 1.65V support required
Output Drive Capability: 24mA output current (high and low)
Propagation Delay: Maximum 4.3ns at 3.3V with 50pF load
Operating Temperature Range: -40°C to 125°C minimum
Compliance: ROHS3 compliant, MSL Level 1

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications) and manufacturer-recommended alternatives (functionally compatible with minor parameter variations).

Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement): SN74LVC04APWE4 and SN74LVC04APW from Texas Instruments are parametric equivalents with identical electrical specifications to the SN74LVC04APWG4. SN74LVC04APW is currently active in production and recommended for new designs requiring the original performance profile.

Manufacturer-Recommended Alternatives: The Nexperia 74LVC04APW,118 extends the minimum supply voltage to 1.2V and maintains the same operating temperature range. The onsemi 74LCX04 series (74LCX04MTCX, MC74LCX04DTG, MC74LCX04DTR2G) operates at a minimum of 2V supply voltage with slightly higher propagation delay (5.2ns) and quiescent current (10 µA). MC74LCX04DTG and MC74LCX04DTR2G support extended temperature range to -55°C.

All substitute parts maintain 14-TSSOP packaging, 6-channel inverter configuration, 24mA output drive, ROHS3 compliance, and MSL Level 1 rating.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC04APWE4 be used as a direct replacement for SN74LVC04APWG4? A: Yes. SN74LVC04APWE4 is a parametric equivalent with identical electrical specifications, supply voltage range (1.65V ~ 3.6V), quiescent current (1 µA), and propagation delay (4.3ns @ 3.3V, 50pF). The primary difference is packaging format (tube vs. other formats).

Q: What is the key difference between Texas Instruments 74LVC04 and onsemi 74LCX04 series? A: The 74LCX04 series has a higher minimum supply voltage (2V vs. 1.65V), higher quiescent current (10 µA vs. 1 µA), and slightly slower propagation delay (5.2ns vs. 4.3ns). These differences may impact low-voltage applications or power-sensitive designs.

Q: Is the Nexperia 74LVC04APW,118 compatible with 1.65V supply applications? A: No. The Nexperia part specifies a minimum supply voltage of 1.2V but operates at a higher quiescent current (40 µA) compared to the original SN74LVC04APWG4 (1 µA). Applications requiring 1.65V operation with minimal power consumption should use Texas Instruments or onsemi alternatives.

Q: Do all substitute parts use the same 14-TSSOP package? A: Yes. All listed substitute parts use 14-TSSOP (0.173", 4.40mm Width) surface mount packaging, ensuring mechanical and electrical compatibility with existing PCB layouts.

Q: Which substitute part supports the widest operating temperature range? A: MC74LCX04DTG and MC74LCX04DTR2G from onsemi support -55°C to 125°C, extending the lower temperature limit by 15°C compared to the original SN74LVC04APWG4 (-40°C to 125°C).
