Substitute Part Grouping Explanation

Substitution eligibility for the 74ALVC162245T 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
Operating Temperature Range: -40°C ~ 85°C (TA)

Electrical Parameters:

Voltage Supply Range: Must encompass or be compatible with 1.65V ~ 3.6V
Current Output Ratings: 12mA/12mA or 24mA/24mA configurations

Physical Parameters:

Mounting Type: Surface Mount
Package / Case: 48-TFSOP (0.240", 6.10mm Width) or equivalent 48-pin TSSOP variants

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

For new designs and ongoing procurement, select from active product status parts. SN74ALVCH16245DGGR (Texas Instruments) and 74ALVC16245DGG,118 (Nexperia USA Inc.) are recommended as primary substitutes. Both maintain the 48-TFSOP package footprint compatible with the original 74ALVC162245T and support the full 1.65V ~ 3.6V supply voltage range with 24mA output current capability.

Secondary Substitutes (Obsolete Status):

Parts with obsolete status (74ALVC16245PAG, 74ALVC16245PAG8, 74ALVCH16245PAG) remain functionally equivalent but carry supply chain risk. These are suitable only when existing inventory is available or when design flexibility permits extended lead times.

Package Considerations:

SN74ALVCH16245DL and SN74ALVCH16245DLR use 48-BSSOP packaging (0.295", 7.50mm Width) instead of 48-TFSOP. These require PCB layout modification and are suitable only when package footprint changes are acceptable.

SN74ALVCH16245DGVR uses 48-TVSOP packaging (0.173", 4.40mm Width), a narrower variant requiring PCB redesign.

Compliance Status:

All listed substitutes maintain REACH Unaffected status and EAR99 ECCN classification, matching the original part's regulatory profile. RoHS3 compliance is confirmed for all active status parts.

Frequently Asked Questions (FAQ)

Q: Can 74ALVC162245T be directly replaced with 74ALVC162245PAG8?

A: Yes. Both parts share identical functional specifications: 2-element, 8-bit non-inverting transceiver with 3-state output in 48-TFSOP package. The 74ALVC162245PAG8 operates at 2.7V ~ 3.6V supply voltage, which is compatible with the original part's 1.65V ~ 3.6V range for applications using 2.7V or higher supply voltages.

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

A: Both series provide identical functional performance as non-inverting transceivers with 2 elements and 8 bits per element. The 74ALVCH series (Texas Instruments, Nexperia) is actively manufactured, while 74ALVC variants show mixed availability. Selection should prioritize active product status for supply chain reliability.

Q: Are SN74ALVCH16245DL and SN74ALVCH16245DLR suitable replacements?

A: Functionally yes, but with package constraints. Both use 48-BSSOP (0.295", 7.50mm Width) instead of 48-TFSOP (0.240", 6.10mm Width). PCB layout modification is required. Use only when package footprint changes are acceptable in your design.

Q: Does supply voltage range affect substitution eligibility?

A: Yes. The original 74ALVC162245T operates at 1.65V ~ 3.6V. Substitutes with narrower ranges (e.g., 2.7V ~ 3.6V) are compatible only if your application uses supply voltages within that narrower range. Parts with wider ranges (e.g., 1.2V ~ 3.6V) are universally compatible.

Q: What is the significance of product status (Active vs. Obsolete)?

A: Active status indicates ongoing manufacturer support and reliable supply availability. Obsolete status indicates discontinued production. For new designs, prioritize active status parts. Obsolete parts are acceptable only for legacy system maintenance with confirmed inventory availability.

Q: Are all listed substitutes RoHS compliant?

A: All active status parts (SN74ALVCH16245DGGR, SN74ALVCH16245DGVR, SN74ALVCH16245DL, SN74ALVCH16245DLR, 74ALVC16245DGG,118, 74ALVCH16245DGG,11) are ROHS3 compliant. Obsolete parts maintain REACH Unaffected status but may have varying RoHS compliance documentation.
