SN74LVC573ADW

The SN74LVC573ADW 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 SN74LVC573ADW 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: The device operates with a supply voltage range of 1.65V to 5.5V, making it suitable for low-voltage applications.
• Input/Output Compatibility: It is compatible with both 3.3V and 5V logic levels, allowing for versatile interfacing with various digital circuits.
• 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 SN74LVC573ADW 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 multiple devices to share the same output line without interference.
• Wide Operating Temperature Range: It can function effectively in a temperature range from -40°C to +125°C, making it suitable for industrial and automotive applications.

Pin Configuration:

• The SN74LVC573ADW 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 include data inputs (D0-D7), output pins (Q0-Q7), latch enable (LE), output enable (OE), and ground (GND) and power supply (VCC) connections.

Applications:

• The SN74LVC573ADW is commonly used in applications such as data buffering, temporary data storage, and interfacing between different logic levels in digital circuits. It is ideal for use in microcontroller and FPGA designs, as well as in communication systems where data integrity and speed are critical.

Conclusion:

The SN74LVC573ADW 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 wide operating temperature range makes it a reliable choice for a broad spectrum of electronic applications.
