Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LS11DRG4 is determined by strict equivalence across the following critical parameters:

• Logic function: 3-channel AND gate with 3 inputs per channel
• Electrical specifications: 4.75V to 5.25V supply voltage, 400µA output high current, 8mA output low current, 0.8V input low threshold, 2V input high threshold, 20ns maximum propagation delay at 5V with 15pF load
• Package format: 14-pin SOIC surface mount configuration
• Thermal operating range: 0°C to 70°C
• Compliance: ROHS3 compliant, MSL Level 1

The SN74LS11DR qualifies as a direct substitute based on identical electrical characteristics, logic configuration, and package specifications. The primary distinction is product status and packaging format (Tape & Reel versus individual packaging).

Parameter Comparison

Engineering Selection Recommendations

The SN74LS11DR is the direct equivalent substitute for the SN74LS11DRG4. Both components are manufactured by Texas Instruments and share identical electrical specifications, logic configuration, and package dimensions. The SN74LS11DR maintains active product status, ensuring continued availability and supply chain reliability. Both parts comply with ROHS3 standards and carry MSL Level 1 moisture sensitivity ratings, indicating no special handling requirements during storage or assembly.

Selection of the SN74LS11DR is appropriate for applications requiring the functional and electrical characteristics of the discontinued SN74LS11DRG4. The primary consideration is packaging format: the SN74LS11DR is supplied in Tape & Reel format, which is standard for high-volume production environments. For applications requiring individual component packaging, alternative sourcing channels or bulk reel procurement may be necessary.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS11DR directly replace the SN74LS11DRG4 in existing designs?

A: Yes. The SN74LS11DR is electrically and functionally identical to the SN74LS11DRG4. Both components feature the same logic configuration (3-channel AND gate with 3 inputs), identical supply voltage range (4.75V to 5.25V), matching output current specifications (400µA high, 8mA low), and identical propagation delay characteristics (20ns at 5V with 15pF load). The 14-SOIC package dimensions are identical, allowing direct PCB footprint compatibility.

Q: What is the difference between the SN74LS11DRG4 and SN74LS11DR?

A: The components are electrically and functionally equivalent. The primary differences are product status and packaging format. The SN74LS11DRG4 is discontinued at DiGi Electronics, while the SN74LS11DR maintains active status. The SN74LS11DR is supplied in Tape & Reel format, which is standard for production quantities, whereas the SN74LS11DRG4 was available in individual packaging.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the SN74LS11DRG4 and SN74LS11DR are ROHS3 compliant and carry identical MSL Level 1 moisture sensitivity ratings. Both parts are REACH unaffected and classified under ECCN EAR99 with HTSUS code 8542.39.0001.

Q: What packaging considerations apply to the SN74LS11DR?

A: The SN74LS11DR is supplied in Tape & Reel (TR) format, which is the standard packaging for production environments. This format is suitable for automated pick-and-place assembly. If individual component quantities are required, the Tape & Reel format can be manually separated or sourced through alternative distribution channels.

Q: Are the input and output logic levels identical between these parts?

A: Yes. Both components specify identical input logic levels (0.8V low threshold, 2V high threshold) and output current capabilities (400µA high, 8mA low), ensuring compatible signal integrity and fan-out characteristics in TTL logic circuits.
