SN74LVC08ARGYRG4 Equivalent & Substitute Parts

Part Overview

The SN74LVC08ARGYRG4 is a 4-channel AND gate logic IC manufactured by Texas Instruments, housed in a 14-VQFN (4.6x4.6) surface mount package. This component is classified as discontinued at DiGi Electronics, which necessitates identification of active equivalent parts to maintain supply chain continuity. The part operates across a wide voltage range of 1.65V to 3.6V, making it suitable for low-voltage digital logic applications. Finding equivalent substitutes ensures project continuity and long-term component availability.

Substitute Part Grouping Explanation

Substitution of the SN74LVC08ARGYRG4 is determined by strict equivalence across the following critical parameters:

Logic function: 4-channel AND gate with 2 inputs per channel
Electrical specifications: Supply voltage range 1.65V ~ 3.6V, quiescent current 1 µA maximum, output drive capability 24mA
Timing characteristics: Maximum propagation delay of 3.9ns at 3.3V with 50pF load
Input/output logic levels: Low threshold 0.7V ~ 0.8V, high threshold 1.7V ~ 2V
Physical package: 14-VFQFN with exposed pad, surface mount configuration
Environmental compliance: ROHS3 compliant, MSL 2 rating

The SN74LVC08ARGYR meets all these criteria as a direct parametric equivalent, with identical electrical and mechanical specifications. The primary distinction is product status and packaging format availability.
