TCA1116 expander equivalent, low voltage 16-bit i2c i/o expander.
1
* I2C to Parallel Port Expander
* Supports partial power down i.e. SDA and SCL are 5V tolerant (<1uA leakage) even when Vcc=0
* Supports 1.8V I2C operation

PRODUCTION D.
This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 1.65-V to 5.5-V VCC operation. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL), serial data.
