74LVC08ADTR2G AND Gate IC Equivalent & Substitute Parts

Part Overview

The 74LVC08ADTR2G is a quad 2-input AND gate logic IC manufactured by onsemi, housed in a 14-TSSOP surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The part operates across a wide supply voltage range of 1.2V to 3.6V and is suitable for low-power logic applications requiring AND gate functionality with four independent channels.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LVC08ADTR2G are qualified based on the following critical parameters:

• Logic Function: All substitutes must implement quad 2-input AND gate functionality with 4 circuits and 2 inputs per circuit
• Package Compatibility: All substitutes must use 14-TSSOP surface mount packaging with identical physical dimensions (0.173", 4.40mm Width)
• Electrical Compatibility: Supply voltage range, output drive capability (24mA), and input logic levels must support the application requirements
• Environmental Compliance: RoHS3 compliance and MSL rating of 1 are maintained across all substitutes

The identified substitutes are grouped into two categories:

1. Series Variant (74LCX08): MC74LCX08DTR2G operates within a narrower supply voltage range (2V ~ 3.6V) with reduced quiescent current but maintains identical package and output drive specifications.

2. Direct Equivalent (74LVC08): 74LVC08APW,118 from Nexperia USA Inc. maintains the same 74LVC series designation, identical supply voltage range, and all electrical parameters, with active product status and higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

74LVC08APW,118 (Nexperia USA Inc.) is the primary substitute for the obsolete 74LVC08ADTR2G. This part maintains identical electrical specifications, supply voltage range, operating temperature range, and package configuration. The part holds active product status with significantly higher inventory availability (17,712 pcs vs. 970 pcs), ensuring long-term procurement viability. Both parts carry ROHS3 compliance and MSL rating of 1, confirming environmental and regulatory equivalence.

MC74LCX08DTR2G (onsemi) serves as an alternative substitute when supply voltage operation is constrained to 2V or higher. This 74LCX series variant offers superior quiescent current performance (10 µA vs. 40 µA), beneficial for battery-powered or ultra-low-power applications. The operating temperature range is limited to -40°C to 85°C, which may restrict use in extended temperature applications. Propagation delay is slightly increased (5.5ns vs. 4.8ns), which is acceptable for non-critical timing paths.

Selection between substitutes depends on application-specific requirements: choose 74LVC08APW,118 for direct replacement with full parameter compatibility and active status; select MC74LCX08DTR2G only when low-power operation and 2V minimum supply voltage are acceptable trade-offs.

Frequently Asked Questions (FAQ)

Q: Can MC74LCX08DTR2G replace 74LVC08ADTR2G in all applications?

A: MC74LCX08DTR2G is compatible only when the supply voltage remains at 2V or higher. Applications requiring operation below 2V must use 74LVC08APW,118 or the original 74LVC08ADTR2G. Additionally, the operating temperature range is limited to -40°C to 85°C, restricting use in extended temperature environments.

Q: Are all substitutes pin-compatible with the original 74LVC08ADTR2G?

A: Yes. All substitutes use the 14-TSSOP package with identical pinout and physical dimensions (0.173", 4.40mm Width), enabling direct PCB replacement without layout modifications.

Q: What is the primary reason for substituting the 74LVC08ADTR2G?

A: The 74LVC08ADTR2G is classified as obsolete. Substitution is necessary to ensure continued design support, procurement availability, and long-term supply chain reliability. The recommended substitute 74LVC08APW,118 maintains full electrical and functional equivalence while offering active product status.

Q: Do all substitutes meet the same environmental and regulatory standards?

A: Yes. All substitutes are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original part's environmental and regulatory certifications.

Q: How do propagation delays compare between substitutes?

A: At 3.3V with 50pF load, propagation delays are: 74LVC08APW,118 at 4.1ns (fastest), 74LVC08ADTR2G at 4.8ns, and MC74LCX08DTR2G at 5.5ns (slowest). For timing-critical applications, 74LVC08APW,118 offers the best performance.
