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.
Package and Quality
Texas Instruments offers the SN74ACT573 in several package options, including the standard DIP and SOIC packages for easy integration into various types of circuit boards. The device is manufactured under TI's stringent quality control standards, ensuring high reliability and performance consistency.
