74ALVT162245DGG:51 Equivalent & Substitute Parts

Part Overview

The 74ALVT162245DGG:51 is a non-inverting transceiver logic IC manufactured by NXP USA Inc., designed for 2-element, 8-bit per element configurations with 3-state output capability. This component operates across dual voltage supply ranges (2.3V–2.7V and 3V–3.6V) and is housed in a 48-TFSOP surface mount package. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ALVT162245DGG:51 is determined by strict parametric alignment across the following criteria:

Core Substitution Parameters:

• Logic type: Transceiver, Non-Inverting
• Number of elements: 2
• Number of bits per element: 8
• Output type: 3-State
• Output current capability: 12mA minimum (high and low)
• Voltage supply ranges: 2.3V–2.7V and 3V–3.6V
• Operating temperature range: -40°C to 85°C
• Package / Case: 48-TFSOP (0.240", 6.10mm Width)
• Mounting type: Surface Mount

All substitute parts listed below meet these parameters without exception. Substitutes are categorized as either manufacturer-recommended (MFR Recommended) or parametric equivalents based on functional and electrical alignment.

Engineering Selection Recommendations

MFR Recommended Substitute: SN74ALVTH162245GR

The SN74ALVTH162245GR, manufactured by Texas Instruments, is the manufacturer-recommended substitute for the 74ALVT162245DGG:51. This part maintains full parametric equivalence across all critical electrical and mechanical specifications. Current inventory availability is 2,136 units. The part is supplied in Tape & Reel (TR) packaging and carries ROHS3 compliance and MSL 1 rating identical to the original component.

Parametric Equivalent (Active Status): 74ALVT162245DGG:11

The 74ALVT162245DGG:11, manufactured by Nexperia USA Inc., is a parametric equivalent with active product status. This part is functionally identical to the original 74ALVT162245DGG:51 across all specified parameters and is currently in active production. Current inventory availability is 874 units. This option provides long-term availability assurance for new designs or ongoing procurement requirements.

Parametric Equivalent: SN74ALVTHR16245GR

The SN74ALVTHR16245GR, manufactured by Texas Instruments, meets all parametric requirements for substitution. Current inventory availability is 3,300 units. This part is supplied in Cut Tape (CT) & Digi-Reel® packaging. Product status is obsolete.

All substitute parts are ROHS3 compliant, carry MSL 1 rating, and maintain identical voltage supply ranges, operating temperature specifications, and package dimensions. Selection should be based on availability requirements, packaging preference, and long-term product lifecycle considerations.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the 74ALVT162245DGG:51?

A: A valid substitute must match all core electrical and mechanical parameters: 2-element, 8-bit per element non-inverting transceiver configuration with 3-state output, 12mA output current capability, dual voltage supply ranges (2.3V–2.7V and 3V–3.6V), operating temperature range of -40°C to 85°C, and 48-TFSOP surface mount package. All listed substitutes meet these criteria without exception.

Q: Can I use SN74ALVTH162245GR as a direct replacement?

A: Yes. The SN74ALVTH162245GR is the manufacturer-recommended substitute and maintains full parametric equivalence with the original part. It is pin-compatible and functionally identical across all specified electrical and mechanical parameters.

Q: What is the difference between the substitute parts listed?

A: The primary differences are manufacturer identity, series designation, product status, and packaging format. The 74ALVT162245DGG:11 (Nexperia) offers active product status, ensuring continued availability. The SN74ALVTH162245GR (Texas Instruments) is the MFR-recommended option. The SN74ALVTHR16245GR (Texas Instruments) is also parametrically equivalent but supplied in Cut Tape & Digi-Reel® format. All three are electrically and mechanically interchangeable.

Q: Is the 74ALVT162245DGG:11 a better choice than the original part?

A: The 74ALVT162245DGG:11 offers the advantage of active product status, meaning it remains in production and will have extended availability. The original 74ALVT162245DGG:51 is obsolete. For new designs or long-term procurement, the active-status equivalent is preferable.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating, matching the original component's environmental and regulatory status.

Q: Can I mix packaging formats (Tape & Reel vs. Cut Tape) in the same assembly?

A: Packaging format does not affect electrical or mechanical compatibility. The choice between Tape & Reel and Cut Tape & Digi-Reel® is a procurement and assembly process consideration, not a functional one. All listed parts are functionally identical regardless of packaging format.
