The 74F573 is a high-performance, octal D-type latch with 3-state outputs from NXP Semiconductors. This integrated circuit is designed to be used in a wide range of applications where storage of 8-bit data is required. It is a part of the 74F series, which is renowned for its fast switching speeds and high data throughput capabilities.

Key Features

• Octal D-type Latches: The 74F573 features eight latches that hold the data present at the D-inputs when the Latch Enable (LE) input is HIGH. The data is retained when the LE is taken LOW.
• 3-State Outputs: Each latch has a corresponding 3-state output that can be used to interface with bus-organized systems. The outputs can be disabled to a high-impedance state, allowing multiple devices to share a common bus without interference.
• Edge-Triggered Latching: The latching operation is edge-triggered, capturing data on the transition from HIGH to LOW on the LE pin, which allows for precise data synchronization.
• Fast Propagation Delay: The device is characterized by its fast propagation delay times, making it suitable for high-speed operations in complex digital systems.

Applications

The 74F573 is versatile and can be used in various applications such as:

• Temporary storage of data
• Bus interfacing in multi-bus architectures
• Data buffering for CPUs and other computing systems
• System control registers
