General Description
The TCA9803 is a dual-channel bidirectional buffer intended for I2C bus and SMBus/PMBus systems.
It provides bidirectional level shifting (up-translation and down-translation) between low voltages (down to 0.8 V) and higher voltages (1.65 V to 3.6 V).
Key Features
- 1 Two-channel bidirectional buffer.
- Integrated current source on B-side, requires no external B-side resistors.
- Ultra-low power consumption.
- No static-voltage offset, low VOL.
- I2C bus and SMBus compatible.
- Operating supply voltage range of 0.8 V to 3.6 V on A-side.
- Operating supply voltage range of 1.65 V to 3.6 V on B-side.
- Active-high repeater enable input.
- Powered-off high impedance I2C bus pins on A- side.
