CLVTH16244AQDLREP Equivalent & Substitute Parts

Part Overview

The CLVTH16244AQDLREP is a non-inverting buffer IC manufactured by Texas Instruments, part of the 74LVTH logic series. This device functions as a 4-element, 4-bit per element buffer with 3-state output capability, designed for low-voltage applications operating between 2.7V and 3.6V. The component is housed in a 48-SSOP package and is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when the original part experiences supply constraints, extended lead times, or when design flexibility allows for alternative manufacturers while maintaining functional equivalence within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLVTH16244AQDLREP is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 4
• Number of Bits per Element: 4
• Output Type: 3-State
• Voltage Supply Range: 2.7V ~ 3.6V (minimum overlap required)
• Package/Case: 48-pin SSOP or TSSOP variants
• Mounting Type: Surface Mount

Allowable Variations:

• Current Output ratings may differ (substitute must meet or exceed application requirements)
• Operating Temperature range may be narrower (substitute must cover minimum -40°C to +85°C)
• Manufacturer and series designation (74LVTH, 74LVT) may vary
• Packaging format (Tape & Reel vs. Bulk) does not affect electrical compatibility

The identified substitute parts maintain functional equivalence across all mandatory parameters while operating within the specified voltage and temperature envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Direct Replacement): The 74LVT162244BDL,118 from NXP Semiconductors is the preferred substitute when package compatibility with 48-BSSOP is required. This part maintains identical package dimensions, voltage supply range, and logic configuration. The reduced output current (12mA vs. 24mA) is acceptable for applications where the original 24mA specification exceeds system requirements. This part carries ROHS3 compliance and MSL-1 rating matching the original device.

Alternative Substitutes (Package Variant): The 74LVTH162244MTX, 74LVTH162244MTD, 74LVT162244MTDX, and 74LVT16244BDGG,118 are functionally equivalent but utilize the 48-TFSOP package (0.240", 6.10mm width) instead of the original 48-BSSOP format. These substitutes are suitable only when PCB layout accommodates the narrower package footprint. The 74LVT16244BDGG,118 provides elevated output current capability (32mA/64mA), making it suitable for applications requiring higher drive strength.

Compliance Considerations: All substitute parts maintain the 2.7V to 3.6V supply voltage range and -40°C to 85°C operating temperature envelope. The original CLVTH16244AQDLREP extends to 125°C; applications requiring operation above 85°C must retain the original part or confirm system requirements do not exceed the substitute temperature limit.

Frequently Asked Questions (FAQ)

Q: Can I use a 48-TFSOP package substitute in place of the 48-BSSOP original?

A: Package substitution is possible only if your PCB layout supports the 48-TFSOP footprint (0.240" width vs. 0.295" for BSSOP). The electrical functionality remains identical, but physical placement and routing must be verified against your design.

Q: What is the difference between 74LVTH and 74LVT series parts?

A: Both series operate within the same 2.7V to 3.6V voltage range and provide identical logic functionality. The primary difference lies in output current specifications and temperature operating ranges. Consult specific datasheets for detailed electrical characteristics.

Q: Are the substitute parts with lower output current (12mA) suitable for my application?

A: Output current sufficiency depends on your load impedance and signal integrity requirements. If the original 24mA specification was selected for margin, 12mA substitutes may be acceptable. If 24mA was a functional requirement, verify load conditions before substitution.

Q: Does the 74LVT16244BDGG,118 with higher output current (32mA/64mA) provide better performance?

A: Higher output current enables faster edge rates and better noise margin when driving capacitive loads. However, increased current also raises power dissipation. Use this variant only when application requirements justify the additional current capability.

Q: What is the impact of the narrower operating temperature range (-40°C to 85°C vs. -40°C to 125°C)?

A: If your application operates entirely within -40°C to 85°C, substitute parts are fully compatible. Applications requiring sustained operation above 85°C must use the original CLVTH16244AQDLREP or confirm system thermal design does not exceed 85°C at the component level.

Q: Are all substitute parts RoHS3 compliant?

A: The 74LVT162244BDL,118 and 74LVT16244BDGG,118 carry explicit ROHS3 compliance certification. Compliance status for Fairchild parts (74LVTH162244MTX, 74LVTH162244MTD, 74LVT162244MTDX) is not specified in available data; verify with manufacturer documentation if RoHS compliance is a design requirement.
