4.1 AXC: Advanced eXtremely Low-Voltage CMOS Translation

Key Features

  • Up and down translation across 0.65 V to 3.6 V
  • Designed with glitch suppression circuitry to improve power sequencing performance
  • Maximum quiescent current (ICCA + ICCB) as low as 6 µA (85°C maximum) and 14 µA (125°C maximum)
  • Up to 500-Mbps support when translating from 1.8 V to 3.3 V
  • VCC Isolation feature – if either VCC input is below 100 mV, all I/Os outputs are disabled and become high impedance
  • Ioff supports partial-power-down mode operation
  • Operating temperature: –40°C to +125°C
  • Packaging options: SC70, SM8, SON, SOT-23, SOT, UQFN, US8, and X2SON
