74LVC16245APVG Equivalent & Substitute Parts

Part Overview

The 74LVC16245APVG is a non-inverting dual 8-bit transceiver with 3-state output manufactured by Renesas Electronics Corporation. This logic IC operates at 3.6V supply voltage and is housed in a 48-SSOP package. The part is currently in Last Time Buy status, making equivalent and substitute parts necessary for ongoing design support and procurement planning. Substitute parts must maintain functional equivalence as a 2-element, 8-bit-per-element transceiver with matching output drive capability and operating temperature range.

Substitute Part Grouping Explanation

Substitution for the 74LVC16245APVG is determined by the following critical parameters: logic type (non-inverting transceiver), element count (2), bits per element (8), output type (3-state), output current capability (24mA minimum), and supply voltage compatibility. The 48-SSOP package is the primary form factor, though functionally equivalent parts in 48-TSSOP or 48-TFSOP packages are acceptable substitutes provided mechanical fit is verified in the target application.

Substitute parts are grouped into two categories:

Category 1: Direct Package Match (48-SSOP) Parts maintaining the original 48-SSOP package footprint with compatible electrical specifications.

Category 2: Alternative Package (48-TSSOP / 48-TFSOP) Parts with equivalent functionality in smaller or alternative surface-mount packages. These require PCB layout verification but offer improved thermal performance and reduced board space.

Engineering Selection Recommendations

For Direct Package Replacement (48-SSOP): SN74LVC16245ADL and SN74LVC16245ADLR from Texas Instruments are the primary direct substitutes. Both maintain the 48-SSOP package, support the required 24mA output current, and are in Active product status. The extended operating temperature range (-40°C to 125°C) and lower minimum supply voltage (1.65V) provide additional design margin compared to the original part.

For Alternative Package Designs (48-TSSOP / 48-TFSOP): When PCB layout permits package migration, 74LCX16245MTDX (onsemi, Active status) and SN74LVC16245ADGGR (Texas Instruments, Active status) offer equivalent functionality with improved thermal characteristics. The 48-TSSOP package reduces board footprint while maintaining 24mA output drive capability.

For Extended Temperature Range Applications: 74LVC16245ADGG,118 (Nexperia) and 74LVCH16245ADGG,11 (Nexperia) support -40°C to 125°C operation with MSL 1 (Unlimited) moisture sensitivity, suitable for harsh environment applications.

Caution on Output Current: 74LVC162245ADGG:11 (Nexperia) provides only 12mA output current. This part is functionally equivalent but not suitable for applications requiring the full 24mA drive capability of the original 74LVC16245APVG.

All recommended substitutes are ROHS3 compliant and carry EAR99 ECCN classification matching the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a 48-TSSOP package part as a direct replacement for the 48-SSOP original? A: Functionally, yes. Electrically, parts like SN74LVC16245ADGG and 74LCX16245MTDX are equivalent. However, the 48-TSSOP package has different pin spacing and footprint. PCB layout modification is required. Verify mechanical fit and trace routing before design release.

Q: What is the difference between 74LVC16245ADGG,118 and 74LVC162245ADGG:11? A: Both are Nexperia parts in 48-TSSOP packages with Active status. The key difference is output current: 74LVC16245ADGG,118 provides 24mA (matching the original), while 74LVC162245ADGG:11 provides only 12mA. Select based on your circuit's output drive requirements.

Q: Why do some substitutes have lower minimum supply voltage (1.2V or 1.65V) than the original (2.7V)? A: Newer logic families like 74LVC and 74LVCH support wider supply voltage ranges. Lower minimum voltage does not affect compatibility in 3.6V applications. The part will operate normally at the original supply voltage.

Q: Is the Texas Instruments SN74LVC16245ADGVR compatible with my 48-SSOP footprint? A: No. The ADGVR variant uses a 48-TVSOP package (0.173" width), which is narrower than the 48-SSOP (0.295" width). This part requires a different PCB footprint. Use SN74LVC16245ADL or SN74LVC16245ADLR for direct 48-SSOP compatibility.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitutes are ROHS3 compliant, matching the original 74LVC16245APVG certification.

Q: What is the MSL (Moisture Sensitivity Level) difference, and does it matter? A: The original part has MSL 3 (168 hours). Most substitutes have MSL 1 (Unlimited), which is superior. Lower MSL values indicate better moisture resistance and longer shelf life. This is an advantage for long-term inventory management.

Q: Can I mix different substitute parts in the same design? A: Yes, provided they meet your electrical requirements (output current, supply voltage, temperature range). However, maintain consistent part selection within a production run to simplify procurement and quality control.
