Output Type: 3-State
Voltage Supply Range: 4.5V ~ 5.5V
Operating Temperature Range: -40°C ~ 85°C minimum
Mounting Type: Surface Mount
Output Current Capability: 32mA (High), 64mA (Low) or compatible

Substitute parts are grouped into two categories:

Direct Functional Equivalents (Same Package): Parts maintaining the 48-BSSOP package with identical electrical specifications and operating temperature range.

Functional Equivalents (Alternative Packages): Parts with identical electrical specifications but different package types (48-TSSOP, 48-TFSOP, 48-TVSOP, 48-CFP), suitable when package footprint flexibility is available.

Extended Temperature Range Variants: Parts with superior operating temperature specifications (-55°C ~ 125°C) that exceed the original part's range, providing enhanced reliability in demanding environments.

Engineering Selection Recommendations

For Direct Package Compatibility (48-BSSOP):

SN74ABT162245DL and SN74ABT162245DLR from Texas Instruments provide direct functional equivalence with identical output current specifications (32mA/64mA) and operating temperature range (-40°C to 85°C). Both parts are active products with RoHS3 compliance. SN74ABT162245DLR is supplied on tape and reel, while SN74ABT162245DL is supplied in tube packaging.

SN74ABT16245ADL from Texas Instruments also maintains 48-BSSOP packaging with matching electrical specifications and active product status with RoHS3 compliance.

CABT16245AMDLREP from Texas Instruments offers 48-BSSOP package compatibility with extended operating temperature range (-55°C to 125°C) and RoHS3 compliance. Output current is reduced to 24mA/48mA, suitable for applications where lower drive capability is acceptable.

For Extended Temperature Performance:

SNJ54ABT16245AWD from Texas Instruments provides the widest operating temperature range (-55°C to 125°C) with matching output current specifications (32mA/64mA). The 48-CFlatPack package requires PCB layout adjustment but delivers superior thermal performance for demanding environments.

For Alternative Package Formats:

74ABT16245BDGG,118 from Nexperia USA Inc. in 48-TSSOP package maintains identical electrical specifications and operating temperature range with active product status and RoHS3 compliance.

SN74ABT162245DGGR and SN74ABT16245ADGGR from Texas Instruments in 48-TSSOP package provide functional equivalence with active status and RoHS3 compliance.

SN74ABT16245ADGVR from Texas Instruments in 48-TVSOP package (narrower 4.40mm width) is suitable for space-constrained designs with identical electrical specifications.

74ABTH162245ADGG,1 from Nexperia USA Inc. in 48-TSSOP package features the 74ABTH series with reduced output low current (12mA) and active product status with RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different package type?

A: Yes, if your PCB layout permits. All substitute parts maintain identical electrical functionality (2-element, 8-bit transceiver, 3-state output, 4.5V-5.5V supply). Package differences are physical only: 48-BSSOP (0.295" width), 48-TSSOP (0.240" width), 48-TVSOP (0.173" width), and 48-CFP are all surface-mount packages with the same pin count and electrical interface. Verify your PCB footprint compatibility before selection.

Q: What is the difference between parts with different output current ratings?

A: Output current capability determines the maximum load-driving capacity. The original 74ABT16245CSSCX specifies 32mA (High) and 64mA (Low). Most active substitutes maintain this specification. CABT16245AMDLREP provides reduced current (24mA/48mA), suitable only if your circuit design does not require full drive capability. 74ABTH162245ADGG,1 provides 32mA (High) but reduced 12mA (Low), acceptable for applications with asymmetric current requirements.

Q: Should I select the extended temperature range part?

A: Extended temperature range (-55°C to 125°C) provides operational margin beyond the original specification (-40°C to 85°C). SNJ54ABT16245AWD and CABT16245AMDLREP offer this capability. Selection depends on your application environment. Standard temperature range parts are sufficient for typical industrial and commercial applications operating within -40°C to 85°C.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All active substitute parts listed carry RoHS3 compliance certification. The original 74ABT16245CSSCX (obsolete) does not specify RoHS status. All active alternatives meet current environmental compliance requirements.

Q: What packaging should I specify for new designs?

A: For new designs, select based on PCB layout requirements and supply chain availability. 48-TSSOP (0.240" width) and 48-BSSOP (0.295" width) are most widely available. 48-TVSOP (0.173" width) is suitable for space-constrained applications. Verify current inventory and lead times with your supplier before finalizing part selection.
