Functional Features

SN74HC573APWRG4 is designed to latch and store data from its inputs (D0-D7) when the latch enable (LE) signal is high. The stored data can be output on the corresponding outputs (Q0-Q7) when the output enable (OE) signal is low. This allows for efficient bus-oriented communication in digital systems.

Advantages and Disadvantages

Advantages

• High-speed operation enables quick data transfer.
• Low power consumption helps conserve energy.
• Wide operating voltage range provides flexibility in various applications.
• Electrostatic discharge protection ensures reliability.

Disadvantages

• Limited number of outputs (8) may not be sufficient for certain applications requiring more outputs.
• TSSOP-20 package may be challenging to solder for some users.

Working Principles

When the latch enable (LE) signal is high, SN74HC573APWRG4 latches the data present at its inputs (D0-D7). The latched data remains stored until a new set of data is latched. The stored data can be output on the corresponding outputs (Q0-Q7) when the output enable (OE) signal is low. This allows for controlled data transfer in a bus-oriented system.

Detailed Application Field Plans

SN74HC573APWRG4 finds applications in various fields, including: - Microcontroller-based systems - Data communication systems - Industrial automation - Automotive electronics - Consumer electronics
