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
