SN74LVTH573PWG4

The SN74LVTH573PWG4 is a high-speed, low-voltage, octal transparent latch designed by Texas Instruments. It is part of the LVTH (Low-Voltage Transceiver with High-Speed) family, which is optimized for use in high-performance digital circuits. Here’s a detailed description of its features and specifications:

General Features:

• Functionality: The SN74LVTH573 is an octal latch that captures data on the rising edge of the clock signal. It allows for transparent operation, meaning that the output follows the input when the latch is enabled.
• Data Inputs/Outputs: It has eight data inputs (D0 to D7) and eight corresponding outputs (Q0 to Q7), allowing for the storage of 8 bits of data.
• Control Inputs: The device includes a clock input (CLK) and an output enable (OE) pin. The OE pin allows for the outputs to be tri-stated, enabling easy bus sharing in multi-device configurations.

Electrical Characteristics:

• Supply Voltage: The device operates with a supply voltage range of 2.7V to 3.6V, making it suitable for low-voltage applications.
• Input/Output Voltage Levels: It is compatible with TTL (Transistor-Transistor Logic) levels, ensuring interoperability with other logic families.
• Propagation Delay: The typical propagation delay from the clock to the output is very low, typically around 3.5 ns at 3.3V, which is ideal for high-speed applications.

Package Information:

• Package Type: The SN74LVTH573PWG4 is available in a TSSOP (Thin Shrink Small Outline Package) with a 20-pin configuration. This compact package is suitable for space-constrained applications.
• Thermal Characteristics: The device has a thermal resistance rating that allows it to operate efficiently without overheating, making it reliable for continuous use in various environments.

Applications:

• Data Storage: It is commonly used in applications requiring temporary data storage, such as in data buffers and latches.
• Bus Interface: The tri-state outputs make it ideal for bus-oriented applications where multiple devices need to share the same data lines.
• High-Speed Logic Circuits: Its fast switching speeds and low power consumption make it suitable for high-speed digital circuits, including communication systems and computing devices.

Additional Features:

• Low Power Consumption: The device is designed to consume minimal power, making it suitable for battery-operated devices.
• ESD Protection: It includes built-in electrostatic discharge (ESD) protection, enhancing its reliability in various operating conditions.

Compliance:

• RoHS Compliant: The SN74LVTH573PWG4 is compliant with the Restriction of Hazardous Substances (RoHS) directive, ensuring it is environmentally friendly.

In summary, the SN74LVTH573PWG4 from Texas Instruments is a versatile and efficient octal latch that is well-suited for a variety of digital applications, particularly where speed and low power consumption are critical. Its combination of features makes it a popular choice among engineers and designers in the electronics industry.
