74LVC16245AEV/G:55 Equivalent & Substitute Parts

Part Overview

The 74LVC16245AEV/G:55 is a non-inverting transceiver IC manufactured by Nexperia USA Inc., designed for 2-element, 8-bit per element logic applications with 3-state output capability. This component operates across a supply voltage range of 1.2V to 3.6V and is housed in a 56-VFBGA package format suitable for surface mount applications.

The 74LVC16245AEV/G:55 carries a product status designation of "Not For New Designs," indicating that while functional and available in inventory, Nexperia has discontinued active development and support for this model line. Organizations requiring this functionality for new projects or seeking long-term supply assurance should evaluate qualified substitute components that maintain electrical and mechanical compatibility while offering current product status or extended availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVC16245AEV/G:55 is determined by strict alignment across the following critical parameters:

Core Functional Requirements:

• Logic type: Transceiver, Non-Inverting
• Element configuration: 2 elements
• Bit width per element: 8 bits
• Output configuration: 3-State

Electrical Compatibility Criteria:

• Supply voltage range must encompass or overlap with 1.2V ~ 3.6V
• Output current capability must meet or exceed 24mA (high and low)
• Operating temperature range must support -40°C ~ 125°C minimum

Mechanical & Compliance Requirements:

• Package type: 56-VFBGA or equivalent 56-pin BGA footprint
• Surface mount mounting type
• RoHS3 compliance
• REACH unaffected status

The 74LVCR162245ZQLR from Texas Instruments qualifies as a substitute based on matching logic type, element count, bit width, output configuration, and package footprint. Voltage and current parameters require evaluation against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

74LVC16245AEV/G:55 (Primary Part): The Nexperia component maintains the widest supply voltage operating range (1.2V ~ 3.6V) and highest output current specification (24mA). Its extended operating temperature range (-40°C to 125°C) supports demanding thermal environments. Current inventory status (780 units) provides immediate availability. However, "Not For New Designs" status indicates limited long-term manufacturer support.

74LVCR162245ZQLR (Substitute Part): The Texas Instruments alternative provides functional equivalence with identical logic architecture and pin configuration. Key trade-offs include reduced supply voltage floor (2.7V minimum versus 1.2V), lower output current capacity (12mA versus 24mA), and narrower operating temperature range (-40°C to 85°C). The "Obsolete" product status indicates this component is also not recommended for new designs. MSL rating of 1 (Unlimited) provides superior moisture handling compared to the primary part's MSL 2 rating. Inventory availability is higher (2,039 units).

Selection Basis: Choose the 74LVC16245AEV/G:55 for applications requiring low-voltage operation below 2.7V, high output current delivery, or extended temperature operation above 85°C. Select the 74LVCR162245ZQLR only when supply voltage remains at or above 2.7V, output current requirements do not exceed 12mA, and operating temperature stays within -40°C to 85°C bounds. Both components carry compliance certifications (ROHS3, REACH unaffected) suitable for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the 74LVCR162245ZQLR directly replace the 74LVC16245AEV/G:55 in all applications?

A: Direct replacement is possible only when application requirements align with the substitute's electrical specifications. The 74LVCR162245ZQLR operates with a minimum supply voltage of 2.7V (versus 1.2V for the primary part) and delivers 12mA output current (versus 24mA). Applications requiring operation below 2.7V or output currents exceeding 12mA cannot use this substitute without circuit redesign.

Q: Are the package footprints identical between these two parts?

A: Both components use 56-pin BGA packages with compatible footprints. The 74LVC16245AEV/G:55 specifies 56-VFBGA (4.5x7mm), while the 74LVCR162245ZQLR uses 56-BGA Microstar Junior (7x4.5mm). The physical dimensions are equivalent, and PCB land patterns are compatible for direct substitution at the board level.

Q: What is the significance of the "Not For New Designs" and "Obsolete" product status designations?

A: "Not For New Designs" indicates the manufacturer has discontinued active development but may continue limited production for existing customers. "Obsolete" signifies the manufacturer has ended all production and support. Both statuses mean long-term supply cannot be guaranteed. For new product development, evaluate current-generation alternatives from the 74LVC or 74LVCR series families.

Q: How do the moisture sensitivity levels (MSL) affect component handling?

A: The 74LVC16245AEV/G:55 carries MSL 2 (1 Year), requiring reflow within one year of package opening and controlled storage conditions. The 74LVCR162245ZQLR carries MSL 1 (Unlimited), allowing indefinite shelf life without moisture bake-out procedures. MSL 1 components offer superior supply chain flexibility and reduced risk of moisture-induced failures during assembly.

Q: Are both parts RoHS3 compliant and suitable for regulated markets?

A: Yes. Both the 74LVC16245AEV/G:55 and 74LVCR162245ZQLR carry ROHS3 compliance certification and REACH unaffected status, meeting environmental and chemical restriction requirements for European and global regulated markets.
