Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74AHCT595D,112 is determined by matching the following critical parameters:

• Logic Type: Shift Register
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: Tri-State
• Function: Serial to Parallel, Serial
• Voltage - Supply: 4.5V ~ 5.5V
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into two categories: parametric equivalents (identical electrical and mechanical specifications) and similar parts (same base functionality with minor variations in product status or operating temperature range).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the 74AHCT595D,112, the following selection criteria apply:

Primary Recommendation: 74HCT595D,112 (NXP Semiconductors) is the preferred parametric equivalent. This part maintains identical electrical specifications, package configuration, and RoHS3 compliance while offering active product status and higher inventory availability (24,102 units in stock).

Alternative Selection: SN74AHCT595DR (Texas Instruments) provides active product status with identical electrical and mechanical specifications. This part is available in Tape & Reel packaging and maintains the full operating temperature range (-40°C ~ 125°C equivalent through the 74AHCT series designation). Inventory availability is substantial (12,821 units in stock).

Secondary Option: 74HCT4094D,112 (Nexperia USA Inc.) is a parametric equivalent with identical core specifications. While currently obsolete, this part maintains all critical electrical and mechanical parameters required for direct substitution.

Temperature Consideration: SN74AHCT595D (Texas Instruments) operates within -40°C ~ 85°C, which is narrower than the original part's -40°C ~ 125°C range. This part is suitable only for applications not requiring operation above 85°C.

All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can 74HCT595D,112 directly replace 74AHCT595D,112?

A: Yes. Both parts are 8-bit shift registers with tri-state output in 16-SOIC packages, operating at 4.5V ~ 5.5V with identical functional specifications. The primary difference is series designation (74HCT vs. 74AHCT) and product status (Active vs. Obsolete).

Q: What is the difference between 74AHCT and 74HCT series designations?

A: Both series are CMOS logic families with compatible electrical specifications for this application. The series designation reflects manufacturer classification; functional equivalence is determined by matching the core part number (595 or 4094) and electrical parameters.

Q: Is SN74AHCT595DR suitable for all applications using 74AHCT595D,112?

A: SN74AHCT595DR is suitable for applications operating within -40°C ~ 85°C. Applications requiring operation above 85°C must use parts with the extended temperature range (-40°C ~ 125°C), such as 74HCT595D,112 or 74HCT4094D,112.

Q: Are there packaging differences between substitute parts?

A: The main part (74AHCT595D,112) is supplied in Tube packaging. Substitute 74HCT595D,112 is available in Bulk packaging, while SN74AHCT595DR is supplied in Tape & Reel (TR) packaging. All parts use identical 16-SOIC (0.154", 3.90mm Width) case dimensions suitable for surface mount assembly.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All listed substitute parts maintain ROHS3 Compliant status and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with current manufacturing standards and environmental regulations.

Q: Which substitute part has the best inventory availability?

A: 74HCT595D,112 (NXP Semiconductors) offers the highest inventory availability at 24,102 units in stock, followed by SN74AHCT595DR (Texas Instruments) at 12,821 units.
