Device identification in the 74xx family: The 7476 and 74LS76 are both dual J–K flip-flop integrated circuits (same function, different subfamily). Evaluate the statement.

Introduction / Context:
The 74xx TTL family includes many functionally similar parts across subfamilies (standard, LS, HC, etc.). Recognizing part numbers and functions avoids selection errors and simplifies substitutions.

Given Data / Assumptions:

• 7476: dual J–K flip-flop (master–slave or edge-triggered depending on variant), TTL.
• 74LS76: low-power Schottky (LS) TTL variant of the 7476 with similar pinout/function.
• “Dual” indicates two flip-flops per package.

Concept / Approach:
In the 74xx family, base numbers denote function while prefixes/suffixes denote logic subfamily and performance differences. Thus 7476 and 74LS76 share the same logic function: two J–K flip-flops in one IC, but differ in electrical characteristics like speed and power.

Step-by-Step Solution:

Verification / Alternative check:
Pin-compatible datasheets show near-identical logic diagrams and truth tables; only electrical parameters differ.

Why Other Options Are Wrong:

Common Pitfalls:
Confusing LS/HC/HCT subfamilies with different functions; overlooking that timing and voltage specs change across subfamilies even when logic function is the same.

Final Answer:
Correct
