74ALVC162240T Equivalent & Substitute Parts

Part Overview

The 74ALVC162240T is a buffer inverting logic IC manufactured by onsemi, designed for 3.6V operation with 4 elements and 4 bits per element configuration. This component features 3-state output capability and is housed in a 48-TSSOP package. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system support and new design implementations where compatible alternatives are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74ALVC162240T are qualified based on the following electrical and mechanical parameters:

Core Compatibility Criteria:

• Logic type: Buffer, Inverting
• Number of elements: 4
• Number of bits per element: 4
• Output type: 3-State
• Supply voltage range: 1.65V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C (TA)
• Package type: 48-pin TSSOP/SSOP family
• Mounting type: Surface Mount

Allowed Parameter Variations:

• Output current capability may exceed the original specification (higher current is acceptable)
• Packaging format within the 48-pin TSSOP/SSOP family is acceptable
• Manufacturer may differ
• Product status may differ (Active status preferred for new designs)

The identified substitute parts maintain functional equivalence through identical logic configuration, voltage specifications, and thermal operating range while offering improved availability and active product status.

Parameter Comparison

Engineering Selection Recommendations

SN74ALVCH16240DGGR (Texas Instruments) is the primary substitute for the 74ALVC162240T. This part maintains identical package dimensions (48-TFSOP, 0.240" width), electrical specifications, and thermal operating range. The device carries Active product status and ROHS3 compliance, providing long-term availability and regulatory alignment. Output current capability is doubled (24mA vs. 12mA), which is acceptable for applications designed around the original specification.

SN74ALVCH16240DL (Texas Instruments) is an alternative substitute with identical electrical and thermal characteristics. This variant uses a wider package format (48-BSSOP, 0.295" width) and is supplied in tube packaging rather than tape & reel. Selection of this part requires PCB layout accommodation for the increased package width. Active product status and ROHS3 compliance are maintained.

Both Texas Instruments alternatives provide superior long-term support compared to the obsolete onsemi part, with higher output current capability suitable for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVCH16240DGGR directly replace 74ALVC162240T without PCB modification?

A: Yes. Both parts use the 48-TFSOP package with identical 0.240" (6.10mm) width and pin configuration. Direct PCB substitution is possible without layout changes.

Q: What is the difference between SN74ALVCH16240DGGR and SN74ALVCH16240DL?

A: The primary difference is package format. SN74ALVCH16240DGGR uses 48-TFSOP (0.240" width) in tape & reel packaging, while SN74ALVCH16240DL uses 48-BSSOP (0.295" width) in tube packaging. Electrical specifications are identical. PCB layout must accommodate the wider BSSOP package for the DL variant.

Q: Why do the Texas Instruments substitutes have higher output current (24mA vs. 12mA)?

A: The SN74ALVCH series is a higher-performance variant of the 74ALVC series. Increased output current capability is a design improvement that maintains backward compatibility while providing enhanced drive capability for applications requiring higher current delivery.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both Texas Instruments substitutes (SN74ALVCH16240DGGR and SN74ALVCH16240DL) are ROHS3 compliant. The original onsemi part RoHS status is not specified in the available data.

Q: What is the moisture sensitivity level for these parts?

A: All three parts (original and substitutes) have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use these parts interchangeably in my existing designs?

A: SN74ALVCH16240DGGR is a direct pin-for-pin replacement with identical package dimensions. SN74ALVCH16240DL requires PCB layout verification due to the wider package format. Both maintain identical electrical and thermal specifications, making them functionally equivalent for the specified operating conditions.
