MAX14591 - Open-Drain Capable Logic-Level Translator

General Description

The MAX14591 is a dual-channel, bidirectional logiclevel translator with the level shifting necessary to allow data transfer in a multivoltage system.

Externally applied voltages, VCC and VL, set the logic levels on either side of the device.

Key Features

  • S Meets Industry Standards.
  • I2C Requirements for Standard, Fast, and High.
  • Speeds.
  • MDIO Open Drain Above 4MHz.
  • S Allows Greater Design Flexibility.
  • Down to 0.9V Operation on VL Side.
  • Supports Above 8MHz Push-Pull Operation S Offers Low Power Consumption.
  • 23µA (typ) VCC Supply Current.
  • 0.5µA (typ) VL Supply Current S Provides High Level of Integration.
  • Pullup Resistor Enabled with One Side Power Supply when TS Is High.
  • 12kI (max) Internal Pullup.

EVALUATION KIT AVAILABLE MAX14591 High-Speed, Open-Drain Capable Logic-Level Translator General Description The MAX14591 is a dual-channel, bidirectional logiclevel translator with the level shifting necessary to allow data transfer in a multivoltage system. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. A logic signal present on the VL side of the device appears as the same logic signal on the VCC side of the device, and vice-versa. The device is optimized for the I2C bus as well as the management data input/output (MDIO) bus where often high-speed, open-drain operation is required. When TS is high, the device allows the pullup to be connected to the I/O port that has the power.
