Features

  • Operates from 1.65V to 3.6V
  • Inputs accept voltages to 5.5V
  • Specified from –40°C to +85°C and –40°C to +125°C
  • Maximum tpd of 5.9ns at 3.3V
  • Typical VOLP (output ground bounce) < 0.8V at VCC = 3.3V, TA = 25°C
  • Typical VOHV (output VOH undershoot) > 2V at VCC = 3.3V, TA = 25°C
  • Supports mixed-mode signal operation on all ports (5V input or output voltage with 3.3V VCC)
  • Ioff supports live insertion, partial-power-down mode, and back-drive protection
