Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ALVT16244DGG,112 is determined by the following critical parameters:

Primary Substitution Criteria:

• Logic type: Buffer, Non-Inverting
• Number of elements: 4
• Number of bits per element: 4
• Output type: 3-State
• Voltage supply ranges: 2.3V–2.7V and 3V–3.6V
• Operating temperature range: -40°C to 85°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Package Compatibility Considerations: Substitutes are grouped into two categories based on package type:

1. Direct Package Match (48-TFSOP): Parts maintaining identical package dimensions (0.240", 6.10mm Width) provide pin-for-pin compatibility without PCB layout modification.

2. Alternative Package Types: Parts with different package designations (48-SSOP, 48-TVSOP) require verification of mechanical fit and pin spacing compatibility, though electrical parameters remain equivalent.

Output Current Variations: The main part specifies 32mA (high) and 64mA (low) output current. Some substitute parts operate at reduced current levels (8mA high, 12mA low), which may affect drive capability in specific circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Highest Compatibility): SN74ALVTH16244GR is the preferred direct substitute. It maintains identical electrical specifications (32mA/64mA output current), operates across the same voltage and temperature ranges, and is housed in the matching 48-TFSOP package (0.240", 6.10mm Width). Both components are ROHS3 compliant with MSL rating 1 (Unlimited). Texas Instruments manufacturing provides equivalent product reliability and documentation support.

Package-Compatible Alternatives: SN74ALVTH16244DL and SN74ALVTH16244DLR preserve electrical equivalence but use the 48-BSSOP package (0.295", 7.50mm Width). These parts require PCB layout modification due to increased package width but maintain identical output current specifications (32mA/64mA).

Reduced Output Current Variants: SN74ALVTH162244 series parts (DL, GR, LR, VR variants) operate at lower output current levels (8mA/12mA). These are electrically compatible but suitable only for applications where reduced drive capability is acceptable. The 162244 base part number indicates this current reduction.

Compact Package Option: SN74ALVTH162244VR and SN74ALVTH16244VR employ the 48-TFSOP package with reduced width (0.173", 4.40mm). These are applicable where PCB space constraints exist, though the 162244 variant includes the current reduction noted above.

All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVTH162244 series parts directly replace the 74ALVT16244DGG,112?

A: SN74ALVTH162244 variants are electrically compatible but operate at reduced output current (8mA/12mA versus 32mA/64mA). Substitution is valid only if the circuit design does not require the higher drive current of the original part. Verify load impedance and fan-out requirements before selection.

Q: What is the difference between 48-TFSOP and 48-BSSOP packages?

A: The 48-TFSOP package measures 0.240" (6.10mm) in width, while 48-BSSOP measures 0.295" (7.50mm). Both are surface-mount packages with identical pin counts and spacing. PCB layout modification is required when switching between these package types.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating 1 (Unlimited), matching the original part's environmental and regulatory specifications.

Q: Which substitute offers the smallest footprint?

A: SN74ALVTH162244VR and SN74ALVTH16244VR use the 48-TFSOP package with 0.173" (4.40mm) width, providing the most compact footprint. Note that the 162244 variant includes reduced output current (8mA/12mA).

Q: Is the Texas Instruments SN74ALVTH16244GR a pin-for-pin replacement?

A: Yes. SN74ALVTH16244GR is a pin-for-pin replacement with identical package dimensions (48-TFSOP, 0.240"), electrical specifications, and operating parameters. No PCB modification is required.

Q: Do all parts operate across the same voltage and temperature ranges?

A: Yes. All listed substitutes operate across 2.3V–2.7V and 3V–3.6V supply ranges with -40°C to 85°C temperature ratings, matching the original 74ALVT16244DGG,112 specification.
