74ALVT16245DGG,112 Equivalent & Substitute Parts

Part Overview

The 74ALVT16245DGG,112 is a non-inverting transceiver IC manufactured by NXP USA Inc., designed for 2-element, 8-bit-per-element applications with 3-state output capability. Operating across dual voltage ranges (2.3V–2.7V and 3V–3.6V), this component is housed in a 48-TSSOP package. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ALVT16245DGG,112 is determined by the following critical parameters:

Functional Equivalence Criteria:

• Logic type: Transceiver, Non-Inverting
• Number of elements: 2
• Number of bits per element: 8
• Output type: 3-State
• Voltage supply ranges: 2.3V–2.7V and 3V–3.6V
• Operating temperature range: –40°C to +85°C

Package Compatibility:

• Primary package: 48-TFSOP (0.240", 6.10mm Width)
• Alternative package: 48-BSSOP (0.295", 7.50mm Width) – functionally compatible with PCB layout adjustment

Compliance Requirements:

• RoHS3 Compliant
• MSL Level 1 (Unlimited)

The substitute parts identified—SN74ALVTH162245DL, SN74ALVTH162245GR, SN74ALVTH162245LR, and SN74ALVTHR16245GR—all meet these core functional and electrical parameters. Variations in output current specifications (12mA vs. 32mA/64mA) and packaging formats (Tape & Reel, Cut Tape & Digi-Reel) represent available options within the same functional class.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain functional and electrical equivalence to the 74ALVT16245DGG,112 across core parameters: transceiver logic type, 2-element 8-bit configuration, 3-state output, dual voltage supply ranges, and operating temperature specification. All substitutes are ROHS3 compliant with MSL Level 1 rating, ensuring regulatory and environmental compatibility.

Package Selection:

• SN74ALVTH162245GR and SN74ALVTHR16245GR maintain the 48-TFSOP package footprint, enabling direct PCB substitution without layout modification.
• SN74ALVTH162245DL and SN74ALVTH162245LR use the 48-BSSOP package, requiring PCB layout adjustment due to increased width (0.295" vs. 0.240").

Availability and Procurement:

• SN74ALVTHR16245GR offers the highest inventory (3,300 pcs), followed by SN74ALVTH162245GR (2,136 pcs).
• SN74ALVTH162245LR provides 1,039 pcs; SN74ALVTH162245DL provides 706 pcs.

Output Current Consideration: The original part specifies 32mA/64mA output current. Texas Instruments substitutes provide dual-mode operation (12mA/12mA or 32mA/32mA), with SN74ALVTHR16245GR limited to 12mA/12mA. Verify application current requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVTH162245DL or SN74ALVTH162245LR be used as direct replacements without PCB modification?

A: No. These parts use the 48-BSSOP package (0.295" width) versus the original 48-TFSOP package (0.240" width). PCB layout adjustment is required. SN74ALVTH162245GR and SN74ALVTHR16245GR maintain the 48-TFSOP footprint and support direct substitution.

Q: Are all substitute parts functionally equivalent in terms of logic operation?

A: Yes. All substitutes are non-inverting transceivers with 2 elements, 8 bits per element, and 3-state output. They operate across identical voltage ranges (2.3V–2.7V and 3V–3.6V) and temperature specifications (–40°C to +85°C).

Q: What is the difference between the Texas Instruments series designations (74ALVTH vs. 74ALVTHR)?

A: Both series maintain functional equivalence. The 74ALVTH series (SN74ALVTH162245DL, SN74ALVTH162245GR, SN74ALVTH162245LR) and 74ALVTHR series (SN74ALVTHR16245GR) are compatible alternatives. Series designation reflects internal design variations that do not affect substitution compatibility for this application.

Q: Does output current specification affect substitution suitability?

A: Output current must be verified against application requirements. The original part specifies 32mA/64mA. Texas Instruments substitutes offer 12mA/12mA or 32mA/32mA operation. SN74ALVTHR16245GR is limited to 12mA/12mA. Confirm that application current demands do not exceed the selected substitute's rating.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All identified substitutes carry ROHS3 Compliant status with MSL Level 1 (Unlimited), matching the original part's environmental and regulatory compliance profile.

Q: What packaging formats are available for procurement?

A: SN74ALVTH162245GR and SN74ALVTHR16245GR are supplied in Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats respectively. SN74ALVTH162245DL is available in Tape & Reel format; SN74ALVTH162245LR in Cut Tape & Digi-Reel format. Select based on assembly process requirements and inventory management practices.
