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, it is no longer recommended for new circuit development. This status necessitates identification of equivalent substitute components that maintain functional compatibility while offering current product support and availability.

Key Parameters

Substitute Part Grouping Explanation

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

Logic configuration: Transceiver, Non-Inverting topology with 2 elements and 8 bits per element Output capability: 3-State output functionality Package compatibility: 56-pin BGA form factor (physical dimensions and pin count) Supply voltage range: Minimum 1.2V to 3.6V maximum Output current drive: Minimum 24mA per output (high and low) Operating temperature range: Minimum -40°C to 125°C maximum Surface mount suitability: Confirmed compatibility with automated assembly processes

The 74LVCR162245ZQLR qualifies as a functional substitute based on matching logic type, element count, bit configuration, output type, package pin count, and surface mount characteristics. Variations in output current drive, supply voltage floor, operating temperature ceiling, and product status represent the primary technical distinctions between the main part and its substitute.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 74LVC16245AEV/G,55 and 74LVCR162245ZQLR must account for the following compliance and availability factors:

The 74LVC16245AEV/G,55 maintains ROHS3 compliance and carries a "Not For New Designs" status, indicating limited long-term support despite current inventory availability of 796 units.

The 74LVCR162245ZQLR is classified as Obsolete, signifying discontinued manufacturing and reduced future availability, though 2039 units remain in current stock. This part also maintains ROHS3 compliance.

Both components satisfy REACH unaffected status and carry identical EAR99 export classification codes.

The 74LVCR162245ZQLR offers superior moisture handling characteristics with MSL 1 (Unlimited) versus MSL 2 (1 Year) for the primary part, reducing storage and handling constraints in manufacturing environments.

Output current drive reduction from 24mA to 12mA in the substitute part requires verification that downstream load impedance and signal integrity requirements remain satisfied within the reduced drive capability.

Supply voltage floor elevation from 1.2V to 2.7V and operating temperature ceiling reduction from 125°C to 85°C necessitate confirmation that system power distribution and thermal operating conditions remain within substitute part specifications.

Frequently Asked Questions (FAQ)

Q: Can the 74LVCR162245ZQLR directly replace the 74LVC16245AEV/G,55 in existing designs?

A: Functional replacement is possible if system design accommodates the reduced output current drive (12mA versus 24mA), elevated minimum supply voltage (2.7V versus 1.2V), and reduced maximum operating temperature (85°C versus 125°C). Pin-to-pin compatibility and logic function equivalence are confirmed.

Q: What are the primary technical differences between these parts?

A: Output current drive capability is reduced by 50% in the substitute. Supply voltage minimum is elevated by 1.5V. Maximum operating temperature is reduced by 40°C. Package dimensions differ slightly (56-BGA Microstar Junior 7x4.5 versus 56-VFBGA 4.5x7), though pin count and BGA footprint remain compatible.

Q: Are both parts suitable for new product development?

A: Neither part is recommended for new designs. The 74LVC16245AEV/G,55 carries explicit "Not For New Designs" status. The 74LVCR162245ZQLR is classified as Obsolete. Alternative current-generation transceiver components should be evaluated for new development programs.

Q: What is the significance of the MSL rating difference?

A: The 74LVC16245AEV/G,55 requires controlled moisture exposure with a 1-year shelf life limit (MSL 2). The 74LVCR162245ZQLR has unlimited shelf life (MSL 1), reducing storage and handling complexity in manufacturing environments.

Q: Are there compliance or certification concerns with either part?

A: Both components maintain ROHS3 compliance, REACH unaffected status, and identical EAR99 export classification. No compliance barriers exist for either part in standard commercial applications.
