CLVTH16244AIZQLREP Equivalent & Substitute Parts

Part Overview

The CLVTH16244AIZQLREP is a non-inverting buffer logic IC manufactured by Texas Instruments, part of the 74LVTH series. This device functions as a 4-element, 4-bit buffer with 3-state output capability, housed in a 56-BGA Microstar Junior package. The part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design requirements and production needs.

Substitute Part Grouping Explanation

Substitution for the CLVTH16244AIZQLREP is determined by the following critical parameters:

Full Parametric Equivalents (56-BGA Package, 4 Elements × 4 Bits):

SN74LVTH16244AZQLR (74LVTH series, Cut Tape packaging)
SN74LVT16244BZQLR (74LVT series, Cut Tape packaging)

Functional Equivalents with Reduced Element Count (20-BGA Package, 2 Elements × 4 Bits):

SN74LVTH244AZQNR (74LVTH series, Cut Tape packaging)
SN74LVT244BZQNR (74LVT series, Cut Tape packaging)

All substitute parts maintain identical electrical specifications: 3-state output, 32mA/64mA output current, 2.7V–3.6V supply voltage, and -40°C to 85°C operating temperature range. The primary distinction between substitutes is the series designation (74LVTH vs. 74LVT) and package configuration (56-BGA vs. 20-BGA).

Engineering Selection Recommendations

For Direct Replacement (Same Pin Count and Package): Select SN74LVTH16244AZQLR or SN74LVT16244BZQLR. Both maintain the 56-BGA Microstar Junior package configuration and 4-element, 4-bit architecture. SN74LVTH16244AZQLR offers higher inventory availability (1821 units) and remains within the 74LVTH series family. Both parts are ROHS3 compliant and carry MSL 1 rating.

For Reduced Element Count Applications: SN74LVTH244AZQNR or SN74LVT244BZQNR provide 2-element, 4-bit configurations in 20-BGA packages. These substitutes are applicable only when circuit design permits reduced buffer element count. SN74LVTH244AZQNR provides the highest inventory level (3364 units).

All substitute parts share identical electrical performance specifications, RoHS compliance status, and moisture sensitivity ratings with the original CLVTH16244AIZQLREP.

Frequently Asked Questions (FAQ)

Q: Can SN74LVTH244AZQNR replace CLVTH16244AIZQLREP directly? A: SN74LVTH244AZQNR is electrically compatible but features a reduced element count (2 elements vs. 4 elements) and different package footprint (20-BGA vs. 56-BGA). Direct PCB replacement is not possible without circuit redesign.

Q: What is the difference between 74LVTH and 74LVT series substitutes? A: Both series maintain identical electrical specifications for this buffer application: 3-state output, 32mA/64mA current ratings, and 2.7V–3.6V supply voltage. Series designation reflects internal design generation; functional performance is equivalent.

Q: Are all substitutes RoHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental certifications.

Q: What packaging difference exists between CLVTH16244AIZQLREP and its substitutes? A: The original part is supplied in Tape & Reel (TR) packaging. Substitute parts are available in Cut Tape (CT) packaging. Both packaging formats are suitable for automated assembly; CT packaging is standard for component distribution.

Q: Can I use a 20-BGA substitute in a design originally specified for 56-BGA? A: No. The 20-BGA and 56-BGA packages have different pin counts, footprints, and element configurations. Substitution requires circuit redesign and PCB layout modification.
