Substitute Part Grouping Explanation

Substitution of the SN74ALS1005D is determined by strict equivalence across the following critical parameters:

• Logic Type: Inverter with 6 channels and 1 input per channel
• Features: Open Collector output configuration
• Electrical Specifications: Supply voltage 4.5V ~ 5.5V, output current 24mA (low), input logic levels 0.8V (low) and 2V (high), propagation delay 30ns @ 5V with 50pF load
• Package: 14-SOIC surface mount form factor
• Operating Temperature Range: 0°C ~ 70°C
• Compliance: ROHS3 Compliant, REACH Unaffected

The SN74ALS1005DR qualifies as a direct substitute based on identical electrical characteristics, package specifications, and compliance certifications. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALS1005DR is the direct substitute for the SN74ALS1005D. Both components are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The SN74ALS1005DR carries Active product status, ensuring continued availability and support, whereas the SN74ALS1005D is designated Last Time Buy. Both parts meet ROHS3 compliance and REACH requirements, making them suitable for applications requiring environmental and regulatory adherence. Selection between these parts should prioritize the SN74ALS1005DR for new designs and ongoing production due to its active status and confirmed supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS1005DR directly replace the SN74ALS1005D in existing designs?

A: Yes. The SN74ALS1005DR is electrically and mechanically equivalent to the SN74ALS1005D. All electrical parameters, including supply voltage, output current, input logic levels, propagation delay, and operating temperature range are identical. The 14-SOIC package dimensions are the same, enabling direct PCB substitution without design modification.

Q: What is the difference between SN74ALS1005D and SN74ALS1005DR?

A: The primary difference is product status and packaging format. The SN74ALS1005D is Last Time Buy with standard packaging, while the SN74ALS1005DR is Active with Cut Tape and Digi-Reel packaging options. Electrically and functionally, both parts are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the SN74ALS1005D and SN74ALS1005DR are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements for industrial and commercial applications.

Q: What is the open collector output configuration?

A: Open collector outputs allow the output to sink current to ground when active (low state) but do not source current when inactive (high state). External pull-up resistors are required to establish the high logic level. This configuration is suitable for applications requiring wired-OR logic or interfacing with different voltage domains.

Q: What are the input logic level thresholds?

A: The SN74ALS1005D and SN74ALS1005DR recognize input voltages below 0.8V as logic low and above 2V as logic high. Input voltages between 0.8V and 2V are undefined and should be avoided in circuit design.
