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

Pinout
| Pinout | Description |
|---|---|
| VA | A-port supply voltage. 1.2 V ≤ VA ≤ 3.6 V, VA ≤ VB |
| VB | B-port supply voltage. 1.65 V ≤ VB ≤ 5.5 V |
| OE | Output enable, by default set to high |
| GND | Ground |
| A1-A8 | Input/Output 1-8, Referenced to VA |
| B1-B8 | Input/Output 1-8, Referenced to VB |
Installation
The 8-bit level shifter breakout device has two functional modes, enabled and disabled. To disable the device, set the OE input low (By default set to High using resistor R2), which places all I/Os in a high impedance state. Setting the OE input high will enable the device.
