The SN74ACT573 is a high-performance, octal transparent D-type latch designed by Texas Instruments. It is a crucial component in digital systems, particularly where temporary storage of data is required. The device features eight latches with 3-state outputs and is part of the 74ACT family, which is renowned for its high-speed operation and compatibility with 5V systems.

Key Features

• Logic Family: The device operates as part of the 74ACT family, which ensures high-speed performance while maintaining compatibility with TTL (Transistor-Transistor Logic).
• Octal Latch: It contains eight D-type latches, which can be used to store bits of data whenever the latch enable (LE) input is high.
• Transparent Operation: The latches are transparent, meaning that when LE is high, the output will change immediately according to the input data, allowing for real-time tracking of the input.
• 3-State Outputs: Each latch has a 3-state output that can be used in bus-oriented systems. The outputs can be set to active high, active low, or high impedance, which is essential for preventing bus contention.
• Wide Operating Voltage Range: The SN74ACT573 operates over a wide voltage range from 4.5V to 5.5V, making it suitable for a variety of logic interfaces.
• Edge-Triggered Latching: The device captures data on the rising edge of the clock signal, ensuring stable data storage.

Applications

The SN74ACT573 is ideal for a broad range of applications including temporary data storage, data buffering, and as an output port for microprocessors. Its high-speed and robust design make it suitable for use in telecommunications, computing, and industrial environments where reliable data handling is essential.
