The SN74LVT573 from Texas Instruments is a high-performance, octal transparent D-type latch designed for 3.3-V V_CC operation. This integrated circuit is part of the LVT family, offering low-voltage operation with the capability to interface to a 5-V system environment.

Key Features

• 3.3-V Operation: Optimized for low-voltage applications, the SN74LVT573 is compatible with the LVT family, ensuring reliable performance at a supply voltage of 3.3V.
• High Drive Capability: With outputs that can drive up to 24 mA, this device can handle a significant load, making it suitable for driving other logic devices or even small LEDs.
• 3-State Outputs: The octal latches feature 3-state outputs, which allow for easy connection to buses or data lines by enabling a high-impedance state, minimizing power consumption when not in use.
• Transparent Latches: Data on the D-input is transferred to the outputs when the latch-enable (LE) input is high, and the data is retained when LE is low, providing a transparent latch functionality.
• Edge-Triggered Latching: The transition of the LE input from low to high captures the data at the D-inputs and holds it, which is ideal for capturing and holding data at precise times.
• Bus-Compatible Outputs: The outputs are designed to be compatible with a wide range of bus interfaces, making this latch an excellent choice for bus-oriented systems.

Applications

The SN74LVT573 is suitable for a variety of applications that require temporary storage of data, including:

• Bus interface/storage
• Data acquisition systems
• Microprocessor or microcontroller interface
• Communication systems
