SN74LVC08AQDREP Equivalent & Substitute Parts

Part Overview

The SN74LVC08AQDREP is a 4-channel 2-input AND gate logic IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This device operates across a 2V to 3.6V supply voltage range and is designed for low-power digital logic applications. The part is currently active in production with RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts may be required due to inventory constraints, regional availability, or specific packaging preferences while maintaining functional and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC08AQDREP is determined by the following critical parameters: logic type (AND gate), circuit count (4 channels), input count (2 inputs per channel), package type (14-SOIC), and mounting method (surface mount). All substitute parts must maintain these core functional specifications. Electrical compatibility is verified through supply voltage range, output current capability, and propagation delay characteristics. The substitute parts listed below meet these requirements within their specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products from established manufacturers with equivalent functional specifications. The 74LVC08AD,118 from Nexperia extends the lower supply voltage limit to 1.2V and supports the full operating temperature range of -40°C to 125°C, matching the original SN74LVC08AQDREP. The 74LCX08M from Fairchild and MC74LCX08DG from onsemi operate within the 2V to 3.6V supply range but limit operating temperature to -40°C to 85°C. All parts maintain RoHS3 compliance and REACH unaffected status. Selection should prioritize temperature range requirements and supply voltage specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the 74LCX08M substitute for the SN74LVC08AQDREP in all applications? A: The 74LCX08M is functionally equivalent in logic operation, package, and output characteristics. However, it operates only to 85°C maximum, compared to 125°C for the original part. Applications requiring the full temperature range must use the 74LVC08AD,118 or SN74LVC08AQDREP.

Q: What is the difference between the 74LVC and 74LCX series? A: Both series provide 4-channel 2-input AND gate functionality in 14-SOIC packages. The 74LVC series (SN74LVC08AQDREP, 74LVC08AD,118) and 74LCX series (74LCX08M, MC74LCX08DG) differ in propagation delay and temperature range specifications. The 74LVC series achieves 4.1ns propagation delay, while 74LCX variants achieve 5.5ns.

Q: Are all substitute parts available in the same packaging format? A: No. The SN74LVC08AQDREP is supplied in Tape & Reel format. The 74LCX08M is supplied in Bulk, and MC74LCX08DG is supplied in Tube. The 74LVC08AD,118 is also supplied in Tape & Reel. Packaging selection depends on assembly requirements and order quantities.

Q: Does the 74LVC08AD,118 support lower supply voltages than the original part? A: Yes. The 74LVC08AD,118 operates from 1.2V to 3.6V, extending the lower voltage limit compared to the SN74LVC08AQDREP which operates from 2V to 3.6V. This provides additional flexibility for low-power applications.

Q: What is the quiescent current difference between parts? A: The SN74LVC08AQDREP, 74LCX08M, and MC74LCX08DG all specify 10 µA maximum quiescent current. The 74LVC08AD,118 specifies 40 µA maximum, which may be significant in ultra-low-power applications.
