Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CABT16245AMDLREP is determined by the following critical parameters:

Core Functional Parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 8
• Output Type: 3-State
• Voltage - Supply: 4.5V ~ 5.5V

Electrical Performance Parameters:

• Current - Output High, Low: Must meet or exceed 24mA, 48mA
• Operating Temperature: Must support -55°C ~ 125°C range or equivalent industrial specification

Physical & Compliance Parameters:

• Mounting Type: Surface Mount
• Package Category: 48-pin SSOP/TSSOP variants
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The 74ABT16245BDGG,118 manufactured by Nexperia USA Inc. qualifies as a manufacturer-recommended equivalent based on matching core functional parameters, supply voltage range, and compliance certifications. Variations in output current capability and operating temperature range represent enhanced or alternative specifications within acceptable substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

Both the CABT16245AMDLREP and 74ABT16245BDGG,118 maintain active product status and full RoHS3 compliance, qualifying them for equivalent use in applications requiring 74ABT series non-inverting transceivers with 2-element, 8-bit configuration and 3-state output.

The CABT16245AMDLREP (Texas Instruments) supports an extended operating temperature range of -55°C ~ 125°C, suitable for industrial and military-grade applications requiring broader thermal specifications.

The 74ABT16245BDGG,118 (Nexperia USA Inc.) provides enhanced output current capability (32mA, 64mA versus 24mA, 48mA) and operates within the -40°C ~ 85°C commercial/industrial temperature range. The package footprint differs slightly (48-TFSOP at 0.240" width versus 48-BSSOP at 0.295" width), requiring PCB layout verification for mechanical compatibility.

Selection between these equivalents depends on application-specific requirements for temperature range, output current capacity, and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the 74ABT16245BDGG,118 directly replace the CABT16245AMDLREP in all applications?

A: Functional compatibility is established through matching logic type, element count, bit configuration, output type, and supply voltage range. However, the operating temperature range differs (-40°C ~ 85°C versus -55°C ~ 125°C). Applications requiring extended low-temperature operation below -40°C or high-temperature operation above 85°C must use the CABT16245AMDLREP. Additionally, the package footprint differs (48-TFSOP versus 48-BSSOP), requiring PCB layout verification.

Q: What is the significance of the output current difference between these parts?

A: The 74ABT16245BDGG,118 provides higher output current capability (32mA, 64mA) compared to the CABT16245AMDLREP (24mA, 48mA). This enhanced current capacity allows the Nexperia device to drive higher-impedance loads or longer signal paths. Applications with marginal current budgets may benefit from the increased capability, while applications designed for the lower current specification remain compatible.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the CABT16245AMDLREP and 74ABT16245BDGG,118 carry ROHS3 Compliant status with Moisture Sensitivity Level 1 (Unlimited), meeting equivalent environmental and regulatory requirements.

Q: What package considerations apply to substitution?

A: The CABT16245AMDLREP uses 48-BSSOP packaging (0.295" width), while the 74ABT16245BDGG,118 uses 48-TFSOP packaging (0.240" width). Both are 48-pin surface mount packages with identical pin counts and configurations. PCB layout and solder reflow profiles must be verified for the specific package geometry to ensure manufacturing compatibility.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For designs requiring extended temperature operation (-55°C ~ 125°C), specify the CABT16245AMDLREP. For commercial/industrial applications within -40°C ~ 85°C with higher output current requirements, the 74ABT16245BDGG,118 offers enhanced performance. Both parts maintain active product status and full compliance certifications.
