SN74LV541ATRGYR

The SN74LV541ATRGYR is a high-speed, low-voltage, octal buffer/driver designed by Texas Instruments. It is part of the 74LV 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 Features:

• Type: Octal Buffer/Driver
• Functionality: The device consists of eight independent buffers/drivers, each with a 3-state output. It is designed to drive capacitive loads and can be used in various applications, including data transmission and signal buffering.
• Logic Levels: The SN74LV541A operates with a supply voltage range of 2.0V to 5.5V, making it compatible with both 3.3V and 5V logic levels.
• Input/Output Compatibility: It is designed to interface with TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) logic families.

Electrical Characteristics:

• Propagation Delay: The typical propagation delay from input to output is around 4.5 ns at 5V, ensuring fast signal transmission.
• Output Drive Capability: The device can drive up to 64 mA of output current, making it suitable for driving multiple loads.
• Power Consumption: The low-voltage operation results in reduced power consumption, which is particularly beneficial in battery-powered applications.

Pin Configuration:

• The SN74LV541ATRGYR is available in a 20-pin TSSOP (Thin Shrink Small Outline Package) form factor, which is compact and suitable for space-constrained designs.
• The pins are arranged to provide easy access to the inputs and outputs, with dedicated enable pins for controlling the output states.

Enable Functionality:

• The device features an active-high enable input (G) for each buffer, allowing for selective activation of the outputs. When the enable pin is high, the corresponding output follows the input; when low, the output is in a high-impedance state.

Applications:

• The SN74LV541ATRGYR is widely used in applications such as:
  • Data bus buffering
  • Signal isolation
  • Level shifting between different voltage domains
  • Driving LEDs and other loads in digital circuits

Package Information:

• Package Type: TSSOP-20
• Dimensions: The TSSOP package is designed for surface mounting, with a small footprint that allows for high-density PCB layouts.

Conclusion:

The SN74LV541ATRGYR from Texas Instruments is a versatile and efficient octal buffer/driver that provides reliable performance in a variety of digital applications. Its low-voltage operation, high-speed capabilities, and robust drive strength make it an excellent choice for modern electronic designs.
