Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74ALS11ADRG4 is determined by strict equivalence across the following critical parameters:

• Logic Function: AND gate with 3 channels and 3 inputs per channel
• Electrical Specifications: Supply voltage range (4.5V ~ 5.5V), output current ratings (400µA high, 8mA low), input logic thresholds (0.8V low, 2V high), and propagation delay (13ns @ 5V, 50pF)
• Package Type: 14-SOIC surface mount package with identical physical dimensions
• Operating Temperature Range: 0°C ~ 70°C
• Compliance Standards: ROHS3 compliance and MSL Level 1

The SN74ALS11ADR meets all these criteria and qualifies as a parametric equivalent. The primary distinction is packaging format: the main part uses tube packaging while the substitute uses Tape & Reel (TR) format. Both parts share identical electrical performance and physical package specifications.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALS11ADR is a direct parametric equivalent to the SN74ALS11ADRG4. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and are housed in the same 14-SOIC package. The SN74ALS11ADR maintains active product status, ensuring continued availability and supply chain reliability compared to the discontinued SN74ALS11ADRG4.

Both parts meet ROHS3 compliance requirements and carry MSL Level 1 rating, indicating no moisture sensitivity constraints during storage and handling. The only operational difference is the packaging format: Tape & Reel versus tube. This distinction affects procurement and assembly processes but does not impact electrical performance or functional compatibility.
