Product Introduction

Overview

The MC74LVX4245DTR2G, produced by onsemi, is a dual-supply octal translating transceiver designed to interface between 5.0 V and 3.0 V buses in mixed-voltage environments. This device is particularly useful in applications such as laptop computers, where a 3.3 V CPU and 5.0 V peripheral devices coexist. The transceiver allows for bidirectional data flow between the two voltage levels, making it an essential component for managing voltage differences in modern electronic systems.

Key Features

  • Bi-directional interface between 5.0 V and 3.0 V buses
  • Control inputs compatible with TTL level
  • Outputs source/sink 24 mA at 5.0 V bus and 12 mA at 3.0 V bus
  • Guaranteed simultaneous switching noise level and dynamic threshold performance
  • Available in SOIC and TSSOP packages
  • Functionally compatible with the 74 Series 245
  • NLV prefix for automotive and other applications requiring unique site and control change requirements; AEC-Q100 qualified and PPAP capable
  • Pb-free, halogen-free/BFR-free, and RoHS compliant

Applications

The MC74LVX4245DTR2G is ideal for mixed-voltage applications such as:

  • Notebook computers using a 3.3 V CPU and 5.0 V peripheral devices
  • Mixed mode dual supply interface solutions where CMOS devices cannot tolerate I/O levels above their applied VCC
  • Systems requiring bidirectional or unidirectional data flow between different voltage levels
  • Automotive and industrial applications requiring robust voltage translation and compliance with automotive standards

Q & A

  1. What is the primary function of the MC74LVX4245DTR2G?

    The primary function is to provide a bi-directional interface between 5.0 V and 3.0 V buses in mixed-voltage environments.

  2. What are the compatible package types for the MC74LVX4245?

    The device is available in SOIC-24 and TSSOP-24 packages.

  3. What is the maximum output source/sink current at 5.0 V and 3.0 V buses?

    The maximum output source/sink current is 24 mA at 5.0 V and 12 mA at 3.0 V.

  4. What is the recommended operating temperature range for the MC74LVX4245?

    The recommended operating temperature range is from −40°C to +85°C.

  5. Is the MC74LVX4245 compatible with automotive standards?
  6. How should the VCCB and VCCA pins be powered up to avoid current issues?

    The safest power-up strategy is to power VCCA before VCCB to avoid current penalties.

  7. What is the propagation delay for data flow from A to B and B to A?

    The propagation delay is typically around 5.1 ns for A to B and 5.4 ns for B to A.

  8. Is the MC74LVX4245 RoHS compliant?
  9. Can the MC74LVX4245 be used in both bidirectional and unidirectional applications?
  10. What are the key benefits of using the MC74LVX4245 in mixed-voltage systems?

    The key benefits include preventing latchup effects, reducing speed degradation, and minimizing power dissipation by providing a dedicated interface between different voltage levels.
