74AHCT245APWJ Equivalent & Substitute Parts

Part Overview

The 74AHCT245APWJ is a non-inverting transceiver logic IC manufactured by Nexperia USA Inc., designed for 8-bit bidirectional data transfer with 3-state output capability. This component operates within the 4.5V to 5.5V supply voltage range and is housed in a 20-TSSOP surface mount package. The part maintains active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified to support design flexibility, inventory management, and supply chain continuity. Substitutes maintain identical electrical performance and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74AHCT245APWJ is determined by strict equivalence across the following critical parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 8mA, 8mA
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 125°C (TA)
• Package / Case: 20-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these criteria. Variations in manufacturer, series designation (74AHCT vs. 74VHCT), packaging format (Tape & Reel vs. Cut Tape), and product qualifications (automotive AEC-Q100) do not affect functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the 74AHCT245APWJ. Selection among equivalents should be based on the following factors:

Manufacturer Availability: Nexperia USA Inc., Toshiba Semiconductor and Storage, and Texas Instruments all provide functionally equivalent devices. Multi-source qualification reduces supply chain risk.

Packaging Format: The 74AHCT245APWJ is supplied in Tape & Reel format. Equivalent parts are available in both Tape & Reel and Cut Tape formats. Selection should align with assembly process requirements and handling procedures.

Product Qualifications: The 74AHCT245PW-Q100J carries AEC-Q100 automotive qualification. This variant is suitable for applications requiring automotive-grade component certification. Non-qualified variants are suitable for general industrial and commercial applications.

Series Designation: Both 74AHCT and 74VHCT series maintain identical electrical specifications within the stated parameters. Series selection does not affect functional compatibility.

Inventory Availability: Current stock levels range from 2000 to 10200 pieces across all equivalents, supporting immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can I substitute 74VHCT245 series parts for 74AHCT245 in my design?

A: Yes. Both series maintain identical electrical performance within the specified parameters: 4.5V to 5.5V supply voltage, 8mA output current, -40°C to 125°C operating temperature, and 3-state output configuration. The series designation does not affect functional compatibility.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Both packaging formats contain identical components. Tape & Reel is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel is supplied in shorter tape segments with individual reel packaging. Selection depends on assembly equipment compatibility and handling procedures.

Q: Is the 74AHCT245PW-Q100J suitable for non-automotive applications?

A: Yes. The AEC-Q100 automotive qualification indicates the part meets automotive reliability standards. This qualification does not restrict use in non-automotive applications. The part is fully compatible with general industrial and commercial designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original 74AHCT245APWJ specification.

Q: Can I mix manufacturers in the same design or production run?

A: Yes. All substitute parts are parametrically equivalent and maintain identical electrical and mechanical specifications. Multi-source components can be used interchangeably within the same design without functional impact.

Q: What determines whether a part is a valid substitute?

A: Valid substitutes must maintain equivalence across all critical parameters: logic type (Transceiver, Non-Inverting), element count (1), bit width (8), output type (3-State), output current (8mA), supply voltage (4.5V ~ 5.5V), operating temperature (-40°C ~ 125°C), package type (20-TSSOP), and compliance certifications (ROHS3, MSL 1).
