FA8201OTR

The noninverting translator of FA8201 uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes. VCCA should not exceed VCCB.

Features

  • 1.2V to 3.6V on A port and 1.65V to 5.5V on B port (VCCA < VCCB)
  • VCC Isolation Feature-If Either VCC Input Is at GND, All Outputs Are in the High-Impedance State
  • EO Input Circuit Referenced to VCCA
  • Low Power Consumption
  • No Power-Supply Sequencing Required, either VCCA or VCCB Can be Ramped First
  • 4-bit Channels
  • DFN 2x3mm²-14L Package
