74LVC08APW,112 Equivalent & Substitute Parts

Part Overview

The 74LVC08APW,112 is a 4-channel 2-input AND gate logic IC manufactured by Nexperia USA Inc., housed in a 14-TSSOP surface mount package. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The 74LVC08 series provides standard AND gate functionality across multiple manufacturers, with variants available in active production status from Texas Instruments and onsemi.

Substitute Part Grouping Explanation

Substitution for the 74LVC08APW,112 is determined by the following critical parameters:

Logic Function: AND gate with 4 channels and 2 inputs per channel
Package Compatibility: 14-TSSOP surface mount package (0.173", 4.40mm width)
Voltage Supply Range: Minimum 1.2V to 3.6V operation
Output Drive Capability: 24mA high and low output current
Propagation Delay: Maximum 4.1ns at 3.3V with 50pF load
Temperature Range: -40°C to 125°C operation
Compliance: ROHS3 compliant, EAR99 classification

Substitute parts must maintain functional equivalence in logic operation, pin compatibility within the 14-TSSOP package family, and electrical performance within the specified voltage and temperature ranges. Parts from the 74LVC and 74LCX series meet these criteria, with variations in quiescent current and minimum supply voltage thresholds.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility)

SN74LVC08APWR, SN74LVC08APWRG3, and SN74LVC08APWT from Texas Instruments are direct functional equivalents. These parts maintain the same 14-TSSOP package, operate across -40°C to 125°C, and deliver superior propagation delay performance (3.9ns versus 4.1ns). All are in active production status with ROHS3 compliance and EAR99 classification. The primary trade-off is a higher minimum supply voltage of 1.65V versus the original 1.2V, and significantly lower quiescent current (1 µA versus 40 µA).

Secondary Substitutes (Package or Temperature Considerations)

SN74LVC08ADB uses a 14-SSOP package instead of 14-TSSOP, requiring PCB layout verification for pin-to-pin compatibility. SN74LVC08AMPWREP and SN74LVC08AQPWREP operate at 2V minimum supply voltage with higher quiescent current (10 µA), suitable for applications not requiring the full 1.2V lower threshold.

Alternative Series (74LCX)

74LCX08MTCX, MC74LCX08DTG, and MC74LCX08DTR2G from onsemi provide functional AND gate logic in 14-TSSOP packages. These parts operate at 2V to 3.6V with slightly longer propagation delay (5.5ns) and reduced operating temperature range (-40°C to 85°C). Selection depends on whether the extended temperature capability to 125°C is required for the application.

Frequently Asked Questions (FAQ)

Q: Can I use SN74LVC08APWR as a direct replacement for 74LVC08APW,112?

A: Yes. Both parts provide 4-channel 2-input AND gate logic in 14-TSSOP packages with identical pin configurations. The SN74LVC08APWR operates across -40°C to 125°C and maintains the same output drive capability (24mA). The minimum supply voltage increases from 1.2V to 1.65V, and quiescent current decreases from 40 µA to 1 µA. Verify your application's minimum supply voltage requirement before selection.

Q: What is the difference between 14-TSSOP and 14-SSOP packages?

A: Both are surface mount packages with 14 pins, but differ in pitch and body width. 14-TSSOP has a 0.173" width, while 14-SSOP has a 0.209" width. PCB footprints are not interchangeable. SN74LVC08ADB uses 14-SSOP and requires layout verification before substitution.

Q: Why do 74LCX08 parts have longer propagation delay than 74LVC08 parts?

A: The 74LCX series exhibits 5.5ns propagation delay at 3.3V compared to 3.9ns for 74LVC08 parts. This is an inherent characteristic of the 74LCX logic family. Applications with strict timing requirements should prioritize 74LVC08 variants.

Q: Can I use onsemi 74LCX08 parts if my application requires operation to 125°C?

A: No. onsemi 74LCX08 parts are rated only to 85°C maximum operating temperature. For applications requiring 125°C operation, select Texas Instruments 74LVC08 variants or Nexperia parts.

Q: What is the significance of the suffix codes (APWR, APWRG3, APWT) in Texas Instruments part numbers?

A: These suffixes indicate packaging and tape configuration. APWR denotes cut tape and digi-reel packaging, APWRG3 indicates tape and reel with specific date code, and APWT specifies tape and reel configuration. All three are functionally identical 74LVC08 AND gates in 14-TSSOP packages.

Q: Is the 74LVC08APW,112 still available for procurement?

A: The 74LVC08APW,112 is classified as obsolete. Active production alternatives from Texas Instruments and onsemi are recommended for new designs and ongoing procurement to ensure supply chain continuity.
