Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVC16245AEVK is determined by the following critical parameters:

• Logic Architecture: Non-inverting transceiver with 2 elements and 8 bits per element
• Output Configuration: 3-state output capability
• Package Compatibility: 56-pin BGA footprint (physical dimensions and pin count)
• Voltage Supply Range: Minimum 1.2V to 3.6V operation
• Output Current Capability: Minimum 24mA per output (high and low)
• Operating Temperature Range: Minimum -40°C to 125°C
• Compliance Standards: ROHS3 compliance and EAR99 classification

The 74LVCR162245ZQLR from Texas Instruments meets the core functional requirements as a non-inverting 2-element, 8-bit transceiver with 3-state output in a 56-pin BGA package. However, specific parameter differences exist that must be evaluated for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 74LVCR162245ZQLR is functionally equivalent to the 74LVC16245AEVK for non-inverting transceiver applications requiring 2-element, 8-bit per element logic with 3-state output. Both components are obsolete and ROHS3 compliant.

Selection between these parts must account for the following parameter differences:

Output Current: The 74LVC16245AEVK provides 24mA output current capability, while the 74LVCR162245ZQLR provides 12mA. Applications requiring higher output drive current must retain the original 74LVC16245AEVK specification.

Voltage Supply Range: The 74LVC16245AEVK operates from 1.2V to 3.6V, while the 74LVCR162245ZQLR operates from 2.7V to 3.6V. Systems requiring operation below 2.7V supply voltage must use the original part.

Operating Temperature Range: The 74LVC16245AEVK supports -40°C to 125°C operation, while the 74LVCR162245ZQLR supports -40°C to 85°C. Applications requiring operation above 85°C must use the original part.

Package Dimensions: Both parts use 56-pin BGA packages with identical pin counts. Physical dimensions differ slightly (4.5x7mm versus 7x4.5mm), requiring verification of PCB layout compatibility.

Moisture Sensitivity: The 74LVCR162245ZQLR has superior moisture handling (MSL 1, Unlimited) compared to the 74LVC16245AEVK (MSL 2, 1 Year), providing advantages for long-term storage and humid environments.

Frequently Asked Questions (FAQ)

Q: Can the 74LVCR162245ZQLR directly replace the 74LVC16245AEVK in all applications?

A: Direct replacement is possible only when application requirements do not exceed the 74LVCR162245ZQLR parameter limits. Verify that output current requirements do not exceed 12mA, supply voltage remains at or above 2.7V, and operating temperature does not exceed 85°C.

Q: What is the primary difference between these two transceiver parts?

A: The 74LVC16245AEVK provides higher output current (24mA), wider supply voltage range (1.2V minimum), and extended temperature range (to 125°C). The 74LVCR162245ZQLR offers lower power consumption and superior moisture resistance.

Q: Are the BGA packages physically compatible?

A: Both parts use 56-pin BGA packages with identical pin assignments. However, physical dimensions differ (4.5x7mm versus 7x4.5mm). PCB layout and solder paste stencil design must be verified for compatibility before substitution.

Q: What compliance certifications apply to both parts?

A: Both the 74LVC16245AEVK and 74LVCR162245ZQLR are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: How does the moisture sensitivity level affect component handling?

A: The 74LVC16245AEVK (MSL 2) requires reflow within one year of packaging opening. The 74LVCR162245ZQLR (MSL 1) has unlimited shelf life after packaging opening, reducing risk of moisture-induced failures in long-term storage or humid manufacturing environments.
