SN74LVC04APWRG4 Equivalent & Substitute Parts

Part Overview

The SN74LVC04APWRG4 is a 6-channel inverter logic IC manufactured by Texas Instruments in a 14-TSSOP surface mount package. This part is discontinued at DiGi Electronics but remains available through inventory stock. The device 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.

Due to the discontinued status of the SN74LVC04APWRG4, equivalent substitute parts from active product lines are necessary for new designs and ongoing production requirements.

Engineering Selection Recommendations

Tier 1 - Direct Replacement (Recommended): SN74LVC04APWR, SN74LVC04APWRG3, and SN74LVC04APWT are the primary substitutes. All three are Texas Instruments 74LVC series parts with identical electrical specifications to the discontinued SN74LVC04APWRG4. These parts maintain the same 1.65V ~ 3.6V supply voltage range, 1 µA quiescent current, and 4.3ns propagation delay. Selection between these three depends on packaging requirements: Cut Tape for SN74LVC04APWR, Tape & Reel for SN74LVC04APWRG3 and SN74LVC04APWT. All are ROHS3 compliant with MSL 1 rating.

Tier 2 - Functional Equivalents (Alternative): 74LCX04MTCX and MC74LCX04DTR2G are onsemi 74LCX series inverters. These parts are functionally equivalent with the same 6-channel, 1-input configuration and 14-TSSOP package. The supply voltage range is narrower (2V ~ 3.6V versus 1.65V ~ 3.6V), quiescent current is higher (10 µA versus 1 µA), and propagation delay is slightly longer (5.2ns versus 4.3ns). These differences are acceptable for applications not requiring the extended low-voltage operation or ultra-low quiescent current of the original part. MC74LCX04DTG offers extended operating temperature range (-55°C ~ 125°C) compared to the original (-40°C ~ 125°C).

Tier 3 - Extended Compatibility (Conditional): 74LVC04APW,118 from Nexperia USA Inc. is a 74LVC series inverter with identical logic configuration and package. This part supports an extended supply voltage range (1.2V ~ 3.6V) but has higher quiescent current (40 µA) and slightly longer propagation delay (4.5ns). Use this part only when the extended low-voltage capability is required and the increased quiescent current is acceptable for the application.

All substitute parts are ROHS3 compliant with MSL 1 rating, matching the original part's environmental and regulatory status.

Frequently Asked Questions (FAQ)

Q: Can I use SN74LVC04APWR as a direct replacement for SN74LVC04APWRG4?

A: Yes. SN74LVC04APWR is a direct electrical equivalent with identical specifications. The only difference is packaging format (Cut Tape & Digi-Reel® versus the original's Cut Tape & Digi-Reel®). Both are Texas Instruments 74LVC series parts with the same 1.65V ~ 3.6V supply range, 1 µA quiescent current, and 4.3ns propagation delay.

Q: What is the difference between SN74LVC04APWRG3 and SN74LVC04APWT?

A: Both are Texas Instruments 74LVC04 inverters with identical electrical specifications. The difference is in packaging format: SN74LVC04APWRG3 is supplied in Tape & Reel (TR) format, while SN74LVC04APWT is also Tape & Reel (TR). Selection depends on your procurement and assembly requirements.

Q: Can I substitute an onsemi 74LCX04 part for the Texas Instruments 74LVC04?

A: Yes, with parameter awareness. The onsemi 74LCX04MTCX and MC74LCX04DTR2G are functionally equivalent 6-channel inverters in 14-TSSOP packages. However, they have a narrower supply voltage range (2V ~ 3.6V versus 1.65V ~ 3.6V), higher quiescent current (10 µA versus 1 µA), and slightly longer propagation delay (5.2ns versus 4.3ns). Use these parts only if your application does not require operation below 2V supply voltage and can tolerate the increased quiescent current.

Q: What does the packaging designation mean (Cut Tape vs. Tape & Reel)?

A: Cut Tape (CT) and Tape & Reel (TR) refer to how the parts are supplied. Cut Tape is supplied in individual strips cut to length, while Tape & Reel is supplied on continuous reels for automated assembly. Both formats contain the same electronic component; the choice depends on your assembly process and volume requirements.

Q: Is the Nexperia 74LVC04APW,118 a suitable substitute?

A: Yes, for applications requiring extended low-voltage operation. The Nexperia part supports 1.2V ~ 3.6V supply voltage (versus 1.65V ~ 3.6V for the original) but has higher quiescent current (40 µA versus 1 µA) and slightly longer propagation delay (4.5ns versus 4.3ns). Use this part only when the lower minimum supply voltage is necessary and the increased quiescent current is acceptable.

Q: Do all substitute parts have the same package dimensions?

A: Yes. All substitute parts use the 14-TSSOP package with 0.173" width and 4.40mm width specification. They are mechanically and electrically compatible for PCB layout and assembly purposes.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the environmental and regulatory status of the original SN74LVC04APWRG4.
