SN74LVC573APWRG4

The SN74LVC573APWRG4 is a high-speed octal transparent latch designed by Texas Instruments, part of their LVC family of logic devices. This component is particularly useful in digital circuits where temporary data storage is required, allowing for the control of data flow in various applications.

Key Features:

1. Functionality: The SN74LVC573APWRG4 is an octal latch, meaning it can hold eight bits of data. It operates in a transparent mode, allowing data to pass through when the latch enable (LE) signal is active. When LE is low, the data is latched and held stable until LE is activated again.

2. Voltage Levels: This device is designed to operate with a wide range of supply voltages, typically from 1.65V to 5.5V, making it suitable for both low-voltage and standard logic applications. It is compatible with various logic families, including TTL and CMOS.

3. Speed: The SN74LVC573APWRG4 features fast propagation delays, which allows for high-speed operation in digital circuits. This makes it ideal for applications requiring quick data processing and transfer.

4. Input/Output Configuration: The device has eight data inputs (D0 to D7) and eight corresponding outputs (Q0 to Q7). The outputs are in a high-impedance state when the latch is not enabled, allowing for easy interfacing with other components in a circuit.

5. Package Type: The SN74LVC573APWRG4 is available in a TSSOP (Thin Shrink Small Outline Package) with a 20-pin configuration. This compact package is suitable for space-constrained applications and provides good thermal performance.

6. Temperature Range: The device is rated for operation over a wide temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications.

7. Power Consumption: The SN74LVC573APWRG4 is designed for low power consumption, which is beneficial in battery-operated devices and applications where energy efficiency is critical.

8. Applications: Common applications include data buffering, temporary data storage, and interfacing between different logic levels in digital systems. It is often used in microcontroller and FPGA designs, as well as in communication systems.

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
• Output Low Voltage (VOL): Typically close to GND
• Propagation Delay: Typically in the range of nanoseconds, depending on the supply voltage and load conditions.

Conclusion:

The SN74LVC573APWRG4 is a versatile and efficient octal latch that provides reliable data storage and transfer capabilities in a compact package. Its wide operating voltage range, low power consumption, and high-speed performance make it an excellent choice for a variety of digital applications.
