24-bit translating 1.65- to 5.5-V I2C/SMBus I/O expander with interrupt, reset & config registers
- Operating power-supply voltage range of 1.65 V to 5.5 V
- Allows bidirectional voltage-level translation and GPIO expansion between:
- 1.8-V SCL/SDA and 1.8-V, 2.5-V, 3.3-V, or 5-V P Port
- 2.5-V SCL/SDA and 1.8-V, 2.5-V, 3.3-V, or 5-V P Port
- 3.3-V SCL/SDA and 1.8-V, 2.5-V, 3.3-V, or 5-V P Port
- 5-V SCL/SDA and 1.8-V, 2.5-V, 3.3-V, or 5-V P Port
- I2C to Parallel port expander
- Low standby current consumption of 1 µA
- Schmitt-Trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs
- Vhys = 0.18 V Typ at 1.8 V
- Vhys = 0.25 V Typ at 2.5 V
- Vhys = 0.33 V Typ at 3.3 V
- Vhys = 0.5 V Typ at 5 V
- 5-V Tolerant I/O ports
