74ABT16373CMTDX Equivalent & Substitute Parts

Part Overview

The 74ABT16373CMTDX is a 16-bit D-Type Transparent Latch manufactured by onsemi, featuring dual 8:8 channel configuration with tri-state output capability. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates within the 4.5V to 5.5V supply voltage range and is housed in a 48-TSSOP surface mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ABT16373CMTDX is determined by strict equivalence across the following critical parameters:

Core Electrical Parameters:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 8:8 (2 Independent Circuits)
• Output Type: Tri-State
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C
• Current - Output High, Low: 32mA, 64mA

Mechanical Parameters:

• Mounting Type: Surface Mount
• Package / Case: 48-TFSOP or 48-BSSOP (compatible pin-to-pin configurations)
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Parameters:

• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS: 8542.39.0001

All substitute parts listed maintain identical electrical specifications and are pin-compatible within their respective package variants. Propagation delay variations are within acceptable operational tolerances for this logic family.

Parameter Comparison

Engineering Selection Recommendations

All three Texas Instruments substitute parts (SN74ABT16373ADGGR, SN74ABT16373ADL, SN74ABT16373ADLR) are active products with ROHS3 compliance, providing long-term availability and regulatory alignment compared to the obsolete onsemi 74ABT16373CMTDX.

Package Selection:

• SN74ABT16373ADGGR maintains the original 48-TFSOP package footprint (0.240", 6.10mm width), enabling direct PCB layout compatibility without redesign.
• SN74ABT16373ADL and SN74ABT16373ADLR use the 48-BSSOP package (0.295", 7.50mm width), requiring PCB layout modification but offering identical electrical performance.

Packaging Format:

• SN74ABT16373ADGGR: Cut Tape (CT) & Digi-Reel® format
• SN74ABT16373ADL: Tube format
• SN74ABT16373ADLR: Tape & Reel (TR) format

Selection should be based on production volume requirements and assembly process compatibility. All parts maintain identical electrical specifications and operating characteristics within the 74ABT logic family.

Frequently Asked Questions (FAQ)

Q: Can SN74ABT16373ADGGR replace 74ABT16373CMTDX without PCB modification?

A: Yes. SN74ABT16373ADGGR maintains identical 48-TFSOP package dimensions (0.240", 6.10mm width) and pin configuration, enabling direct substitution without PCB layout changes.

Q: What is the difference between the three Texas Instruments substitutes?

A: The primary differences are package type and packaging format. SN74ABT16373ADGGR uses 48-TFSOP (0.240" width), while SN74ABT16373ADL and SN74ABT16373ADLR use 48-BSSOP (0.295" width). All three maintain identical electrical specifications. Packaging formats differ: Cut Tape & Digi-Reel, Tube, and Tape & Reel respectively.

Q: Are there propagation delay differences between the main part and substitutes?

A: Yes. The 74ABT16373CMTDX specifies 1.4ns propagation delay, while all Texas Instruments substitutes specify 4.1ns. Both values are within the 74ABT logic family specifications and do not affect functional compatibility in standard applications.

Q: Do the substitute parts meet current environmental and compliance requirements?

A: Yes. All Texas Instruments substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original onsemi part does not specify RoHS status.

Q: Which substitute should be selected for high-volume production?

A: SN74ABT16373ADLR (Tape & Reel format) is optimized for high-volume automated assembly. SN74ABT16373ADGGR (Cut Tape & Digi-Reel) supports medium-volume production. SN74ABT16373ADL (Tube) is suitable for lower-volume or manual assembly processes.

Q: Are all parts pin-compatible?

A: SN74ABT16373ADGGR is pin-compatible with 74ABT16373CMTDX. SN74ABT16373ADL and SN74ABT16373ADLR are electrically equivalent but use a different package footprint (48-BSSOP vs. 48-TFSOP), requiring PCB redesign.
