Substitute Part Grouping Explanation

Substitution of the SC74AC11DR2G is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Logic type: AND Gate configuration
• Circuit count: 3 channels minimum
• Input count: 3 inputs per channel
• Package: 14-SOIC surface mount
• Supply voltage range: 2V to 6V compatibility
• Propagation delay specifications: 8ns maximum at 5V, 50pF load
• Output current capability: 24mA high and low
• Operating temperature range: -40°C to 85°C

The MC74AC11DR2G qualifies as a direct substitute based on identical logic architecture, circuit topology, input/output configuration, and package specifications. Both components operate within the same voltage and temperature parameters, ensuring functional equivalence in circuit applications.
