Product Introduction

Overview

The SN74LVC125APWT is a quadruple bus buffer gate produced by Texas Instruments. This device is designed for operation within a voltage range of 1.65V to 3.6V, making it versatile for various applications. It features independent line drivers with 3-state outputs, allowing each output to be disabled when the associated output-enable (OE) input is high. This component is suitable for use in mixed 3.3V/5V system environments due to its ability to accept input voltages up to 5.5V.

  • General-purpose buffering and signal translation
  • High-speed digital circuits requiring low propagation delay
  • Systems requiring 3-state output control

Q & A

  1. What is the operating voltage range of the SN74LVC125APWT?

    The operating voltage range is from 1.65V to 3.6V.

  2. What is the maximum operating temperature of the SN74LVC125APWT?

    The maximum operating temperature is 125°C.

  3. How many buffers does the SN74LVC125APWT have?

    The device has four independent buffers.

  4. What is the maximum propagation delay at 3.3V?

    The maximum propagation delay at 3.3V is 4.8ns.

  5. Can the inputs accept voltages higher than the supply voltage?
  6. What is the typical output ground bounce and VOH undershoot at 3.3V?

    The typical output ground bounce (VOLP) is less than 0.8V, and the VOH undershoot is greater than 2V at VCC = 3.3V, TA = 25°C.

  7. Is the SN74LVC125APWT RoHS compliant?
  8. What is the logic family of the SN74LVC125APWT?

    The logic family is LVC.

  9. How many output states does each buffer have?

    Each buffer has 3-state outputs.

  10. What is the recommended way to ensure high-impedance state during power up or power down?

    The OE should be tied to VCC through a pull-up resistor.
