Statement-wise Verification

• Statement 1 - Correct.
  Programmable Logic Devices allow implementation of combinational logic without fixed hardware connections.
  A PAL traditionally has a programmable AND plane and fixed OR plane.
• Statement 2 - Correct.
  PLA allows both AND and OR arrays to be programmable, offering maximum flexibility.
  A PLA provides programmable AND and OR planes for high flexibility
• Statement 3 - Correct.
  PAL provides programmable AND array while keeping OR array fixed.
  A PLA provides programmable AND and OR planes for high flexibility, while a PAL traditionally has a programmable AND plane and fixed OR plane.

Core Concept

Programmable logic devices realize logic functions through programmable interconnect arrays. A PLA provides programmable AND and OR planes for high flexibility, while a PAL traditionally has a programmable AND plane and fixed OR plane.

Formula / Key Relationship

PLA: programmable AND + programmable OR; PAL: programmable AND + fixed OR.

Why the Other Options Are Wrong

Option A is incorrect because it omits correct statement(s) 3. Option B is incorrect because it omits correct statement(s) 1. Option C is incorrect because it omits correct statement(s) 2.

Exam Shortcut / Approach

Use PLA for flexibility; PAL for simpler/faster structures.

Common Mistake

Do not swap PLA and PAL programmability.

Quick Revision

Programmable Logic Device Architecture is linked with PLA and PAL, Programmable Logic and Digital Electronics. Use PLA for flexibility; PAL for simpler/faster structures.
