Product Introduction

Overview

The 74HCT573PW,118, produced by Nexperia USA Inc., is an 8-bit D-type transparent latch with 3-state outputs. This device is part of the 74HCT family, which is compatible with TTL (Transistor-Transistor Logic) input levels. It features latch enable (LE) and output enable (OE) inputs, allowing for flexible control over data storage and output states. When the LE input is HIGH, the latches are transparent, and the output will change each time the corresponding D-input changes. When LE is LOW, the latches store the information present at the inputs. A HIGH on the OE input causes the outputs to assume a high-impedance OFF-state, without affecting the state of the latches.

Key Features

  • 8-bit D-type transparent latch with 3-state outputs.
  • Latch enable (LE) and output enable (OE) inputs for flexible control.
  • CMOS low power dissipation and high noise immunity.
  • Inputs include clamp diodes, allowing the use of current limiting resistors to interface inputs to voltages in excess of VCC.
  • Wide supply voltage range from 4.5 to 5.5 V.
  • Inputs and outputs on opposite sides of the package, facilitating easy interface with microprocessors.

Applications

The 74HCT573PW,118 is versatile and can be used in various applications across different industries, including:

  • Automotive electronics for safety and efficiency improvements.
  • Industrial environments for energy-efficient and reliable solutions, such as in Uninterruptible Power Supply (UPS) systems and motor drives.
  • Consumer and mobile devices where low power consumption and high noise immunity are crucial.
  • Microprocessor and microcomputer systems as input or output ports.

Q & A

  1. What is the primary function of the 74HCT573PW,118?

    The 74HCT573PW,118 is an 8-bit D-type transparent latch with 3-state outputs, allowing it to store and output data based on the latch enable and output enable inputs.

  2. What are the logic switching levels for the 74HCT573PW,118?

    The logic switching levels for the 74HCT573PW,118 are TTL (Transistor-Transistor Logic) levels.

  3. What is the operating temperature range for the 74HCT573PW,118?

    The operating temperature range is from -40°C to 125°C.

  4. What is the package type for the 74HCT573PW,118?

    The package type is TSSOP20 (SOT360-1).

  5. How does the latch enable (LE) input affect the device?

    When LE is HIGH, the latches are transparent, and the output will change each time the corresponding D-input changes. When LE is LOW, the latches store the information present at the inputs.

  6. What is the effect of a HIGH on the output enable (OE) input?

    A HIGH on the OE input causes the outputs to assume a high-impedance OFF-state, without affecting the state of the latches.

  7. Can the 74HCT573PW,118 be used with voltages in excess of VCC?

    Yes, the inputs include clamp diodes, allowing the use of current limiting resistors to interface inputs to voltages in excess of VCC.

  8. What are some common applications for the 74HCT573PW,118?

    Common applications include automotive electronics, industrial environments, consumer and mobile devices, and microprocessor and microcomputer systems.

  9. What is the propagation delay for the 74HCT573PW,118 at VCC = 4.5 V?

    The propagation delay is typically 17 ns, with a maximum of 45 ns.

  10. Is the 74HCT573PW,118 RoHS compliant?

    Yes, the 74HCT573PW,118 is RoHS compliant.
