Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ABT2952CSCX is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the 74ABT logic family
• Voltage Supply Range: Identical 4.5V ~ 5.5V operating range
• Output Configuration: 3-State output capability required
• Current Ratings: Output high and low current specifications of 32mA and 64mA
• Operating Temperature: Matching -40°C ~ 85°C temperature range
• Package Type: 24-SOIC surface mount package with identical physical dimensions (0.295", 7.50mm Width)
• Bits per Element: 8-bit configuration per element

The SN74ABT2952ADWR from Texas Instruments meets these substitution criteria while maintaining active product status and current manufacturing availability.
