Product Overview: 74LVC543APW

The 74LVC543APW by NXP is a high-performance, low-voltage octal transceiver featuring non-inverting 3-state bus compatible outputs. This integrated circuit is designed for 2.7V to 3.6V VCC operation, making it suitable for interfacing with 3.3V logic devices. It is part of the LVC (Low-Voltage CMOS) family, which is known for its low power consumption and high-speed operation.

Key Features

  • Logic Type: Octal Transceiver with Non-Inverting 3-State Outputs
  • Operating Voltage: 2.7V to 3.6V, with 5V tolerant inputs for interfacing with 5V logic levels without damage.
  • High-Speed: Capable of propagating delays as low as 3.7ns, providing efficient data transfer between buses.
  • Power Consumption: Low power dissipation with a typical ICC of 40 µA, even at high speeds.
  • Package: The device comes in a TSSOP (Thin Shrink Small Outline Package) with 20 pins, providing a compact footprint for space-constrained applications.
  • Compatibility: Input and output interface capability to systems at 5V supply.
  • Multiple Gating Options: Includes an output enable (OE) and a directional control (DIR) for each 4-bit section.


The 74LVC543APW is versatile and can be used in a variety of applications. It is particularly well-suited for interfacing between different voltage domains in a system, and can be used in:

  • Communication systems
  • Computers and computer peripherals
  • Data storage devices
  • Microprocessor or microcontroller-based systems
