SSI (Small Scale Integration) has:
Multiple Choice Options
- A✓ Correct Option
Less than 10 transistors
- B
Less than 20 transistors
- C
Less than 30 transistors
- D
Less than 50 transistors
Detailed Technical Solution & Explanation
Integrated circuits are classified based on transistor density: SSI (Small Scale Integration) contains fewer than 10 to 12 gates or equivalent transistors. MSI (Medium Scale) contains 10–100 gates, LSI contains 100–1,000 gates, and VLSI exceeds 1,000 gates.
Option Analysis:
•
Option A (Less than 10 transistors): Correct. Early SSI fabrication was defined by having up to 10 transistors (or a few logic gates) integrated onto a single silicon chip.
•
Option B (Less than 20 transistors): Incorrect. Standard integration metrics benchmark SSI below 10 transistors/gates; 10–100 transitions into MSI.
•
Option C (Less than 30 transistors): Incorrect. 30 transistors fall squarely within the Medium Scale Integration (MSI) tier.
•
Option D (Less than 50 transistors): Incorrect. 50 transistors represent intermediate MSI logic (such as decade counters or 4-bit adders).
