常見問題解答

What is TC74ACT541FT?

The TC74ACT541FT is a octal buffer/line driver with 3-state outputs, designed by Toshiba Semiconductor and Storage. It is ideal for applications requiring signal buffering and driving capabilities, such as interfacing between different logic voltage levels, bus transceivers, and general-purpose logic-level translation.

How Does TC74ACT541FT Work?

The TC74ACT541FT works by taking input signals and buffering them to drive output lines with high current capability and 3-state control for bus-oriented applications. It features eight non-inverting buffers with three-state outputs, providing a high degree of flexibility and versatility for signal transmission and reception.

How Many Pins does TC74ACT541FT have and What are the Functions of the Pinout Configuration?

The TC74ACT541FT is housed in a 20-pin TSSOP (Thin Shrink Small Outline Package) package. The pinout configuration includes:

  • OE: Output Enable input for all buffers.
  • A1 to A8: Input buffer enable or 3-state control for each buffer.
  • Y1 to Y8: Non-inverting buffer outputs.
  • GND: Ground pin.
  • VCC: Positive power supply pin.

What are the Pros and Cons of TC74ACT541FT?

Pros:

  • High Current Capability: Can drive outputs with high current, suitable for bus-oriented applications.
  • 3-State Outputs: Provides flexibility in controlling the output state for bus applications.
  • Wide Voltage Range: Supports wide operating voltage range, enabling compatibility with various logic levels.
  • High Speed: Offers fast propagation delay times for rapid signal transmission.
  • Compact Package: The 20-pin TSSOP package is space-efficient, suitable for compact designs.

Cons:

  • Complex Control: Requires careful consideration of the output enable and input control signals for proper operation.
  • External Pull-Up/Pull-Down Resistors: May require external resistors for proper bus termination and control.
  • Power Consumption: High current capability may lead to relatively higher power consumption.

Are There Any Equivalents/Alternatives to TC74ACT541FT for Recommendation?

  • The SN74ACT541 from Texas Instruments is a similar octal buffer/line driver with 3-state outputs.
  • Alternatives to the TC74ACT541FT include the MC74ACT541 from ON Semiconductor and the IDT74ALVC541 from Integrated Device Technology.
