SN74LVTH373PWRE4

The SN74LVTH373PWRE4 is a high-speed, low-voltage, octal transparent latch designed by Texas Instruments. It is part of the LVTH (Low-Voltage TTL Compatible High-Speed CMOS) family, which is known for its compatibility with TTL logic levels while operating at lower supply voltages. Here’s a detailed description of its features and specifications:

General Features:

• Functionality: The SN74LVTH373 is an octal transparent latch, meaning it can hold and store data when enabled. It allows data to pass through when the latch is in a transparent state and holds the data when the latch is disabled.
• Data Inputs: It has eight data inputs (D0 to D7) that can accept standard TTL input levels.
• Control Inputs: The latch is controlled by a single enable input (LE - Latch Enable). When LE is high, the data present at the inputs is transferred to the outputs. When LE is low, the outputs retain the last data state.
• Output Configuration: The outputs (Q0 to Q7) are in a tri-state configuration, allowing multiple devices to connect to a common bus without interference. This means the outputs can be driven high, low, or placed in a high-impedance state.

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 and Output Voltage Levels: The input high voltage (VIH) is typically around 2.0V, while the input low voltage (VIL) is around 0.8V. The output high voltage (VOH) is typically close to the supply voltage, and the output low voltage (VOL) is typically near ground.
• Propagation Delay: The typical propagation delay from the latch enable to the output is around 3.5 ns at 3.3V, making it suitable for high-speed applications.
• Power Consumption: The device is designed for low power consumption, which is critical in battery-operated devices and energy-efficient applications.

Package Information:

• Package Type: The SN74LVTH373PWRE4 is available in a TSSOP (Thin Shrink Small Outline Package) with 20 pins, which provides a compact footprint suitable for space-constrained designs.
• Thermal Characteristics: The package is designed to dissipate heat effectively, ensuring reliable operation under various conditions.

Applications:

The SN74LVTH373 is commonly used in various applications, including:

• Data buffering and storage in digital circuits.
• Bus interface applications where multiple devices need to share data lines.
• Temporary data storage in microcontroller and FPGA designs.
• Any application requiring high-speed data latching with low power consumption.

Additional Information:

• RoHS Compliance: The "PWRE4" suffix indicates that the part is compliant with the Restriction of Hazardous Substances (RoHS) directive, making it suitable for environmentally friendly designs.
• Manufacturer Support: Texas Instruments provides extensive documentation, including datasheets and application notes, to assist engineers in integrating the SN74LVTH373 into their designs.

In summary, the SN74LVTH373PWRE4 is a versatile and efficient octal transparent latch that combines high-speed performance with low-voltage operation, making it an excellent choice for modern digital applications.
