Commercial TTL/CMOS families commonly offer octal (8-bit) packages: many basic latches and flip-flops are available as ICs with eight elements sharing a common clock or enable.

Difficulty: Easy

Correct Answer: Correct

Explanation:


Introduction / Context:
Digital systems operate on bytes and words, so industry-standard ICs frequently bundle eight similar elements in a single package. Examples include octal latches, octal flip-flops, and octal bus drivers with common control lines for compact board designs.



Given Data / Assumptions:

  • Octal parts like 74HC373/74HC573 (octal transparent latches) and 74HC273/74HC374 (octal edge-triggered flip-flops) are widely used.
  • Common control pins (CLK, EN, OE) simplify synchronous interfacing to 8-bit buses.
  • Both TTL-compatible and CMOS families exist.


Concept / Approach:
Grouping eight storage elements matches 8-bit data paths, minimizing pin count and routing complexity while improving timing uniformity. A shared clock/enable ensures coherent updates across the byte-wide register or latch.



Step-by-Step Solution:

Select an octal device appropriate to needs (latch vs flip-flop, tri-state outputs as required).Connect shared control (CLK/EN/OE) to the bus timing signals.Wire D[7:0] and Q[7:0] to the system data path.Leverage the common control to capture or present a full byte atomically.


Verification / Alternative check:
Consult typical microprocessor-era schematics: address/data latching commonly uses octal packages for convenience and standardization.



Why Other Options Are Wrong:
It is not restricted to dynamic latches or ASIC libraries; off-the-shelf octal ICs are ubiquitous. Saying “Incorrect” ignores decades of standard logic practice.



Common Pitfalls:
Confusing dual or quad packages (like 7474 dual D FF) with octal; both exist. Designers must pick the form factor that matches the datapath width.



Final Answer:
Correct
