Substitute Part Grouping Explanation

Substitute parts for the N74F244DB,112 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 4
• Output Type: 3-State
• Current - Output High, Low: 15mA, 64mA
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: 0°C ~ 70°C (TA)
• Package / Case: 20-SSOP (0.209", 5.30mm Width)
• Mounting Type: Surface Mount
• Base Product Number: 74F

Substitute parts are grouped into two categories: Direct Manufacturer Substitutes (same part number from alternative manufacturers) and Parametric Equivalents (functionally identical parts with different packaging or product status).

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the N74F244DB,112, the SN74F244DBR (Texas Instruments) is the primary substitute. This part maintains full electrical and mechanical compatibility while offering active product status, ensuring long-term availability and supply chain continuity.

The SN74F244DB (Texas Instruments) serves as a secondary option with identical electrical specifications. However, its Last Time Buy status indicates limited future availability, making it suitable only for near-term procurement requirements.

Both Texas Instruments alternatives comply with ROHS3 and maintain MSL Level 1 ratings, matching the original part's environmental and regulatory compliance profile.

Frequently Asked Questions (FAQ)

Q: Can SN74F244DBR be used as a direct replacement for N74F244DB,112?

A: Yes. The SN74F244DBR is electrically and mechanically identical to the N74F244DB,112. All functional parameters, including logic type, element count, bit configuration, output type, current ratings, supply voltage, operating temperature, and package dimensions are equivalent.

Q: What is the difference between SN74F244DBR and SN74F244DB?

A: Both parts are parametrically identical. The primary difference is packaging format and product status. SN74F244DBR is supplied in Cut Tape (CT) & Digi-Reel format with Active status, while SN74F244DB is supplied in Tube format with Last Time Buy status.

Q: Why is the original N74F244DB,112 marked as obsolete?

A: Obsolete status indicates the manufacturer (NXP USA Inc.) has discontinued production. Active equivalents from Texas Instruments ensure design continuity and component availability.

Q: Are there any thermal or performance differences between the substitutes?

A: No. All three parts operate within identical temperature ranges (0°C ~ 70°C) and deliver the same output current specifications (15mA high, 64mA low).

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. The 20-SSOP package dimensions are identical across all three parts, allowing direct PCB footprint compatibility without layout modifications.

Q: What compliance certifications apply to the substitute parts?

A: Both Texas Instruments alternatives maintain ROHS3 compliance and MSL Level 1 ratings, matching the original part's regulatory and environmental qualifications.
