Substitute Part Grouping Explanation

Substitution of the CY74FCT2541CTSOCT is determined by strict equivalence across the following critical parameters:

• Logic function: Non-inverting buffer with 1 element, 8 bits per element
• Output configuration: 3-state output
• Electrical specifications: 15mA/12mA output current, 4.75V–5.25V supply voltage range
• Operating temperature range: -40°C to 85°C
• Package type: 20-SOIC surface mount
• Compliance certifications: ROHS3, REACH Unaffected, EAR99

The CY74FCT2541TSOCT meets all these criteria and is therefore a parametric equivalent. The primary distinction between the main part and its substitute is packaging format and product status.

Parameter Comparison
