Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74ACTQ16245MTD is determined by the following critical parameters:

Functional Requirements:

• 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

Electrical Requirements:

• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C (TA)

Physical Requirements:

• Mounting Type: Surface Mount
• Package / Case: 48-TFSOP (0.240", 6.10mm Width) or 48-BSSOP (0.295", 7.50mm Width)
• Supplier Device Package: 48-TSSOP or 48-SSOP

Substitute parts are grouped into two categories:

Direct Substitutes (Same Package): Parts maintaining the 48-TFSOP package with identical electrical specifications.

Compatible Substitutes (Alternative Package): Parts with equivalent electrical performance but different physical packaging (48-BSSOP), suitable for applications where package footprint differences are acceptable.

Parametric Equivalents (Different Voltage Range): Parts with identical functional and physical characteristics but operating at different supply voltage ranges (2V ~ 3.6V), requiring circuit design verification before substitution.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Package, Same Voltage):

The 74ACT16245DGGR (Texas Instruments, Active status) is the primary recommended substitute. It maintains identical electrical specifications, package configuration (48-TFSOP), and supply voltage range (4.5V ~ 5.5V). Active product status ensures long-term availability and supply chain stability.

The 74FCT162245CTPAG (IDT, Active status) provides an alternative direct replacement with equivalent performance and active product status, offering supply diversification.

For Compatible Substitution (Alternative Package, Same Voltage):

The 74ACT16245DLR (Texas Instruments, Active status) is suitable for applications where package footprint differences are acceptable. This part uses the 48-BSSOP package (0.295", 7.50mm Width) instead of 48-TFSOP, maintaining all electrical specifications and supply voltage requirements. Active product status supports long-term deployment.

The 74ACT16245DL (Texas Instruments, Last Time Buy status) provides equivalent functionality but with limited availability due to Last Time Buy status.

For Low-Voltage Applications:

The 74LCX16245MTD (onsemi, Last Time Buy status) operates at 2V ~ 3.6V supply voltage. This part is suitable only for applications designed for low-voltage operation and requires verification that the lower supply voltage range is compatible with system requirements. Last Time Buy status indicates limited future availability.

Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original 74ACTQ16245MTD.

Frequently Asked Questions (FAQ)

Q: Can I use 74ACT16245DGGR as a direct replacement for 74ACTQ16245MTD?

A: Yes. Both parts are non-inverting transceivers with 2 elements, 8 bits per element, 3-state output, 24mA output current, 4.5V ~ 5.5V supply voltage, and -40°C ~ 85°C operating temperature. The 48-TFSOP package is identical. The primary difference is manufacturer (Texas Instruments vs. onsemi) and product status (Active vs. Obsolete).

Q: What is the difference between 48-TFSOP and 48-BSSOP packages?

A: Both are 48-pin surface mount packages for this transceiver class. The 48-TFSOP has a width of 0.240" (6.10mm), while the 48-BSSOP has a width of 0.295" (7.50mm). The BSSOP package is physically larger. Substitution between these packages requires PCB layout verification to ensure footprint compatibility.

Q: Can I substitute the 74LCX16245MTD for the 74ACTQ16245MTD?

A: Functional substitution is possible only if your circuit design supports the lower supply voltage range of 2V ~ 3.6V. The 74LCX16245MTD is not a direct replacement for 5V systems. Verify that all connected components and power supply specifications are compatible with the lower voltage range before substitution.

Q: Why is the 74ACTQ16245MTD listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Active substitutes such as 74ACT16245DGGR and 74FCT162245CTPAG are recommended for new designs and ongoing system support.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, consistent with the original 74ACTQ16245MTD specifications.

Q: What is the Moisture Sensitivity Level (MSL) for substitute parts?

A: The 74ACT16245DGGR, 74ACT16245DL, 74ACT16245DLR, 74FCT162245ATPAG, and 74FCT162245CTPAG all maintain MSL 1 (Unlimited), identical to the original part. The 74LCX16245MTD has MSL 2 (1 Year), requiring different handling and storage procedures.
