SN74LVC573ADWR

The SN74LVC573ADWR is a high-speed, low-voltage octal transparent latch designed by Texas Instruments. It is part of the LVC family of logic devices, which are known for their low power consumption and high-speed performance. Here’s a detailed description of its features and specifications:

General Description:

• Type: Octal Transparent Latch
• Functionality: The SN74LVC573ADWR is designed to store data in a transparent manner. When the latch enable (LE) input is high, the data present at the inputs (D0-D7) is passed to the outputs (Q0-Q7). When LE goes low, the outputs hold the last state of the inputs.

Key Features:

• Voltage Range: Operates with a supply voltage range of 1.65V to 5.5V, making it suitable for a variety of low-voltage applications.
• Input/Output Compatibility: The device is compatible with both 3.3V and 5V logic levels, allowing for versatile interfacing with other components.
• High-Speed Operation: The device can operate at high speeds, with a maximum propagation delay of around 5 ns at 3.3V, making it suitable for high-frequency applications.
• Low Power Consumption: The SN74LVC573ADWR features low static and dynamic power consumption, which is beneficial for battery-operated devices.
• Tri-State Outputs: The outputs can be placed in a high-impedance state, allowing for easy bus sharing among multiple devices.
• Latch Enable and Output Control: The device includes a latch enable (LE) input and an output enable (OE) input, providing control over when data is latched and when outputs are active.

Pin Configuration:

• The SN74LVC573ADWR is available in a 20-pin TSSOP (Thin Shrink Small Outline Package) form factor, which is compact and suitable for space-constrained applications.
• The pins are arranged to provide easy access to the data inputs, outputs, and control signals.

Applications:

• The SN74LVC573ADWR is commonly used in applications such as data buffering, temporary data storage, and interfacing between different logic levels in digital circuits.
• It is suitable for use in consumer electronics, automotive systems, and industrial automation.

Electrical Characteristics:

• Input High Voltage (VIH): Minimum of 0.7 × VCC
• Input Low Voltage (VIL): Maximum of 0.3 × VCC
• Output High Voltage (VOH): Typically close to VCC when loaded
• Output Low Voltage (VOL): Typically close to GND when loaded
• Operating Temperature Range: Typically from -40°C to +125°C, making it suitable for a wide range of environmental conditions.

Conclusion:

The SN74LVC573ADWR from Texas Instruments is a versatile and efficient octal transparent latch that provides high-speed data handling capabilities while maintaining low power consumption. Its compatibility with various voltage levels and its compact package make it an ideal choice for modern digital applications.
