Availability of standard parts: “Parity generator and parity checker circuits are available as single IC packages.” This statement is ________.

Introduction / Context:Classic small- and medium-scale integration (SSI/MSI) catalogs include standard building blocks for common digital functions, including parity generation and checking. Recognizing the availability of these functions as off-the-shelf ICs is useful in both legacy maintenance and educational labs.

Given Data / Assumptions:

• Parity generator: computes parity bit from data.
• Parity checker: detects parity mismatches on received data.
• Commercial logic families (TTL, CMOS) provide such functions as fixed packages.

Concept / Approach:Manufacturers have long offered parity generator/checker chips. While part numbers vary by family, their presence in logic catalogs demonstrates that both functions exist as single ICs. Some chips even combine generation and checking in the same package for convenience.

Step-by-Step Solution:

Verification / Alternative check:Datasheets and textbooks list parity generator/checker ICs in common TTL/CMOS lines, confirming availability as single, dedicated parts. In modern designs, equivalent functionality can also be done in programmable logic, but the discrete ICs still exist for specific needs.

Why Other Options Are Wrong:

• Incorrect/logic-family limitations: Availability does not hinge on a particular high-voltage family or exotic logic like ECL; standard TTL/CMOS offer such parts.

Common Pitfalls:Believing parity must require a microcontroller or CPLD; overlooking simple MSI solutions; conflating parity with more complex error-correcting codes which indeed require more logic.

Final Answer:Correct
