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
