Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LVC125ARGYRG4 is determined by strict equivalence across the following critical parameters:

• Logic function: Non-inverting buffer with 4 elements, 1 bit per element
• Output configuration: 3-state output
• Electrical specifications: 24mA output current (high and low), 1.65V to 3.6V supply voltage range
• Operating temperature range: -40°C to 125°C
• Package type: 14-VQFN (4.6x4.6) with exposed pad
• Compliance: ROHS3 compliant, MSL 2 rating

The SN74LVC125ARGYR meets all these criteria and qualifies as a parametric equivalent. The primary distinction between the main part and its substitute is packaging format and product status.
