Substitute Part Grouping Explanation

Substitution of the 74ALVC16245DTR is determined by strict equivalence across the following critical parameters:

Logic Type: Transceiver, Non-Inverting
Number of Elements: 2
Number of Bits per Element: 8
Output Type: 3-State
Current - Output High, Low: 24mA, 24mA
Voltage - Supply: 1.65V ~ 3.6V (minimum requirement)
Operating Temperature: -40°C ~ 85°C (TA)
Package / Case: 48-TFSOP or compatible 48-pin packages
Supplier Device Package: 48-TSSOP or equivalent

Substitute parts are grouped into two categories:

Parametric Equivalents: Parts with identical electrical specifications and the same 48-TSSOP package footprint.

Similar Parts: Parts with compatible electrical specifications but variations in supply voltage range, output current ratings, package dimensions, or series designation (74ALVC vs. 74ALVCH). These require design verification for specific application constraints.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent):

74ALVC16245MTDX from Fairchild Semiconductor is the closest parametric equivalent, matching all electrical specifications and package footprint of the 74ALVC16245DTR. This part is currently active in production.

Active Production Alternatives with Full Compatibility:

74ALVC16245DGG,118 (Nexperia) and 74ALVCH16245DGG,11 (Nexperia) are active production parts with identical output current ratings and operating temperature range. Both are ROHS3 compliant. The 74ALVC16245DGG,118 maintains the 74ALVC series designation and supports supply voltages down to 1.2V. The 74ALVCH16245DGG,11 operates in the 74ALVCH series with the same voltage and current specifications.

Texas Instruments Active Options:

SN74ALVCH16245DGVR and SN74ALVCH16245DL/DLR from Texas Instruments are active production parts with identical electrical performance. SN74ALVCH16245DGVR uses a 48-TVSOP package (0.173" width), while SN74ALVCH16245DL and SN74ALVCH16245DLR use a 48-SSOP package (0.295" width). Both package variants differ from the original 48-TFSOP footprint and require PCB layout verification.

Voltage-Constrained Alternatives:

74ALVC16245PAG and 74ALVC16245PAG8 (Renesas) and 74ALVCH16245PAG (Renesas) support minimum supply voltage of 2.7V, which is higher than the original 1.65V specification. These parts are obsolete but available in inventory. Use only if application supply voltage is confirmed at 2.7V or higher.

Compliance Consideration:

The original 74ALVC16245DTR is RoHS non-compliant. All active production substitutes listed (Nexperia and Texas Instruments variants) are ROHS3 compliant, meeting current regulatory requirements for new designs.

Frequently Asked Questions (FAQ)

Q: Can I use 74ALVC16245PAG as a direct replacement for 74ALVC16245DTR?

A: 74ALVC16245PAG is electrically compatible if your application operates at supply voltages of 2.7V or higher. The original part supports 1.65V minimum; this substitute requires 2.7V minimum. Verify your circuit's supply voltage specification before selection.

Q: What is the difference between 74ALVC and 74ALVCH series parts?

A: Both series are non-inverting bus transceivers with identical functional specifications for this product category. The 74ALVCH designation represents a variant series. Electrical performance and pin compatibility are maintained across both series for these part numbers.

Q: Why do some substitutes have different package codes (48-TSSOP vs. 48-SSOP vs. 48-TVSOP)?

A: Package codes indicate physical dimensions and lead pitch. 48-TSSOP (0.240" width) matches the original footprint. 48-SSOP (0.295" width) and 48-TVSOP (0.173" width) are physically different and require PCB layout redesign. Verify package compatibility with your PCB design before selection.

Q: Are all substitute parts currently in production?

A: No. The original 74ALVC16245DTR and several Renesas variants (74ALVC16245PAG, 74ALVC16245PAG8, 74ALVCH16245PAG) are obsolete. Active production parts include 74ALVC16245MTDX (Fairchild), 74ALVC16245DGG,118 (Nexperia), 74ALVCH16245DGG,11 (Nexperia), and all Texas Instruments variants (SN74ALVCH16245DGVR, SN74ALVCH16245DL, SN74ALVCH16245DLR).

Q: What is the significance of RoHS compliance for this part?

A: The original 74ALVC16245DTR is RoHS non-compliant. All active production substitutes are ROHS3 compliant, meeting current environmental and regulatory standards. For new designs or products subject to RoHS requirements, select from active production parts with ROHS3 compliance.

Q: Can I substitute 74ALVC162245PAG8 for 74ALVC16245DTR?

A: 74ALVC162245PAG8 has a different base product number (74ALVC162245 vs. 74ALVC16245) and supports output current options of 12mA or 24mA. While functionally similar, this part represents a different product line. Verify datasheet compatibility and electrical requirements before use.

Q: Which substitute offers the best long-term availability?

A: Texas Instruments variants (SN74ALVCH16245DGVR, SN74ALVCH16245DL, SN74ALVCH16245DLR) and Nexperia parts (74ALVC16245DGG,118, 74ALVCH16245DGG,11) are currently active in production with established supply chains. These are recommended for new designs requiring long-term component availability.
