Key Features

  • 3-State Outputs: The device features two output enables (1OE and 2OE), each controlling four of the 3-state outputs, allowing for high-impedance OFF-state when nOE is HIGH.
  • Wide Supply Voltage Range: Operates from 1.2 V to 3.6 V, making it suitable for mixed 3.3 V and 5 V environments.
  • CMOS Low-Power Consumption: Low power consumption due to CMOS technology.
  • Schmitt-Trigger Action: Inputs have Schmitt-trigger action, making the circuit tolerant of slower input rise and fall times.
  • Overvoltage Tolerant Inputs: Inputs are overvoltage tolerant up to 5.5 V.
  • I OFF Circuitry: Provides partial power-down mode operation, preventing backflow current when the device is powered down.
  • ESD Protection: Exceeds 2000 V HBM and 1000 V CDM.

Applications

  • Digital Circuit Design: Suitable for use in various digital circuits requiring buffer or line driver functions.
  • Mixed Voltage Environments: Can be used as translators in mixed 3.3 V and 5 V environments).
  • Partial Power Down Applications: Ideal for applications where partial power-down is required, thanks to the I OFF circuitry).
  • General Purpose Logic: Can be used in general-purpose logic applications where low power consumption and high-speed operation are required).
