8 Bit Level Shifter Breakout

The 8-bit level shifter is an 8-bit non-inverting shifter breakout board with the powerful and compact IC TXB0108 and VCCA Voltage Range: 1.2V-3.6V and VCCB Voltage Range: 1.65V-5.5V that acts as a bridge between applications with differing source voltage and input-output voltage levels.

Features

  • VCC Isolation Feature – If Either VCC Input Is at GND, All Outputs Are in the High-Impedance State
  • Low power consumption
  • High conversion speed, up to 60Mbps in push-pull applications, up to 2Mbps in open-drain applications
  • Bidirectional automatic conversion, no direction control needed
  • OE Input Circuit Referenced to VCCA
  • Ioff Supports Partial-Power-Down Mode Operation

Specifications

  • VCCA Voltage Range: 1.2V-3.6V
  • VCCB Voltage Range: 1.65V-5.5V
  • Conditions of Use: VCCB>VCCA
  • Working Current: 30uA
  • Support Port: push-pull, open-drain
  • Conversion Speed: push-pull 60Mbps(MAX)\open-drain 2Mbps(MAX)
  • Working Temperature Range: -30℃~75℃
  • IC - TXB0108
  • Power Consumption - 4μA Max ICC
