Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ALVT16823DGG,112 is determined by strict alignment of the following critical parameters:

• Functional equivalence: Dual 9-bit D-type flip-flop with positive edge triggering and master reset capability
• Output configuration: Tri-state, non-inverted outputs
• Package compatibility: 56-TFSOP surface mount package (0.240", 6.10mm Width)
• Clock frequency: 250 MHz maximum operation
• Electrical specifications: Supply voltage range, propagation delay, output current ratings, and quiescent current
• Compliance standards: RoHS3 compliance and MSL rating

The SN74ALVCH16823DGGR from Texas Instruments meets these substitution criteria. Both devices share identical functional architecture, package form factor, and core electrical performance characteristics within specified operating ranges.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALVCH16823DGGR is a direct functional substitute for the obsolete 74ALVT16823DGG,112. Both devices are ROHS3 compliant and carry MSL rating 1, meeting identical environmental and regulatory requirements.

The SN74ALVCH16823DGGR offers active product status from Texas Instruments, ensuring ongoing availability and supply chain support. The substitute device maintains full functional compatibility with identical package geometry, pin configuration, and core logic operation.

The SN74ALVCH16823DGGR demonstrates improved quiescent current performance (40 µA versus 100 µA) and extended supply voltage range (1.65V ~ 3.6V versus 2.3V ~ 3.6V), providing enhanced flexibility for power-sensitive and low-voltage applications.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVCH16823DGGR directly replace the 74ALVT16823DGG,112 without circuit modification?

A: Yes. Both devices share identical pin configuration, package form factor (56-TFSOP), and functional architecture. No circuit redesign is required for direct substitution.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Nexperia versus Texas Instruments), product status (obsolete versus active), and minor variations in quiescent current, supply voltage range, and propagation delay specifications. Functional operation and package compatibility remain identical.

Q: Are there any supply voltage compatibility concerns?

A: The SN74ALVCH16823DGGR supports a wider supply voltage range (1.65V ~ 3.6V) compared to the 74ALVT16823DGG,112 (2.3V ~ 2.7V, 3V ~ 3.6V). Applications operating within the original part's voltage range will function without modification on the substitute device.

Q: Does the substitute part meet the same compliance and environmental standards?

A: Yes. Both devices are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level). Regulatory and environmental certifications are equivalent.

Q: What is the significance of the propagation delay difference?

A: The 74ALVT16823DGG,112 specifies 3.1ns propagation delay at 50pF load, while the SN74ALVCH16823DGGR specifies 4.6ns at 30pF load. Both values remain within acceptable timing margins for standard 250 MHz logic applications. Application-specific timing analysis is required for critical path evaluation.
