74LVC16244APVG Equivalent & Substitute Parts

Part Overview

The 74LVC16244APVG is a non-inverting buffer IC manufactured by Renesas Electronics Corporation, designed for logic signal buffering applications with 4 elements and 4 bits per element. This device features 3-state output capability and operates across a 2.7V to 3.6V supply voltage range in a 48-SSOP package.

The 74LVC16244APVG is classified as obsolete. Substitute parts are necessary to maintain design continuity and ensure long-term component availability for new production runs and system updates.

Substitute Part Grouping Explanation

Substitution of the 74LVC16244APVG is determined by the following critical parameters:

Logic Type: Buffer, Non-Inverting (4 elements, 4 bits per element)
Output Type: 3-State
Output Current Capability: 24mA high and low
Supply Voltage Range: Minimum 2.7V support required
Operating Temperature Range: Minimum -40°C to 85°C support required
Package Compatibility: 48-SSOP or 48-TSSOP footprints
RoHS3 Compliance: Required for regulatory alignment

Substitute parts are grouped into two categories based on package type: 48-SSOP (same footprint as original) and 48-TSSOP (alternate footprint with different pitch). All substitutes maintain the core logic functionality, 3-state output architecture, and non-inverting buffer operation.

Engineering Selection Recommendations

For direct footprint replacement of the 74LVC16244APVG in 48-BSSOP package, select from Texas Instruments SN74LVC16244ADL or SN74LVC16244ADLR. Both parts maintain 24mA output current capability, support the required 2.7V minimum supply voltage through their 1.65V ~ 3.6V range, and extend operating temperature to -40°C ~ 125°C. These parts are in active production status with MSL 1 rating.

For applications requiring 48-TSSOP package footprint, the Renesas 74LVC16244APAG provides direct functional equivalence with active product status and improved moisture sensitivity (MSL 1). The NXP 74LVC16244ADGG,118 offers extended supply voltage range (1.2V ~ 3.6V) and temperature range (-40°C ~ 125°C) in 48-TFSOP package.

All recommended substitutes maintain ROHS3 compliance and 3-state output architecture. Parts with reduced output current (12mA from Texas Instruments 74LVCH series) are suitable only where load requirements do not exceed 12mA per output.

Frequently Asked Questions (FAQ)

Q: Can I use SN74LVC162244ADL as a direct replacement for 74LVC16244APVG?

A: SN74LVC162244ADL is functionally compatible but with reduced output current (12mA versus 24mA). It maintains the same 48-BSSOP package, non-inverting buffer logic, and 3-state output. Use this part only if your application does not require 24mA output current capability.

Q: What is the difference between 48-SSOP and 48-TSSOP packages?

A: 48-SSOP (Shrink Small Outline Package) has a 0.295" width with 7.50mm body width. 48-TSSOP (Thin Shrink Small Outline Package) has a 0.240" width with 6.10mm body width. These are different footprints and require separate PCB layouts. The 74LVC16244APVG uses 48-BSSOP (0.295" width), which is compatible with 48-SSOP footprints.

Q: Why do some substitutes have lower output current ratings?

A: The 74LVCH series (12mA output) and certain 74LVC variants (12mA output) are designed for lower-power applications. The original 74LVC16244APVG and its direct equivalents (SN74LVC16244ADL/ADLR, SN74LVCH16244ADL) maintain 24mA output current. Select based on your circuit's load requirements.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts maintain RoHS3 compliance, consistent with the original 74LVC16244APVG specification.

Q: What is the significance of MSL rating differences?

A: The original part has MSL 3 (168 hours maximum floor life). All active substitute parts have MSL 1 (unlimited floor life), providing superior moisture handling and extended shelf life for manufacturing operations.

Q: Can I use 74LVC16244APAG as a drop-in replacement?

A: 74LVC16244APAG is functionally equivalent but uses 48-TFSOP package instead of 48-BSSOP. It requires a different PCB footprint. Electrical specifications and output current (24mA) are identical to the original part.
