Description

The TCAL6416 device provides general purpose parallel input/output (I/O) expansion for the two-line bidirectional I2C bus (or SMBus) protocol. The device can operate with a power supply voltage ranging from 1.08V to 3.6V on the I2C bus side (VCCI) and a power supply voltage ranging from 1.08V to 3.6V on the Pport side (VCCP).

Key Features

  • Operating power-supply voltage range of 1.08V to 3.6V
  • Allows bidirectional voltage-level translation and GPIO expansion between 1.2V, 1.8V, 2.5V, and 3.3V I2C bus and p-ports
  • Low standby current consumption of 1µA typical at 1.8V
  • 1-MHz fast mode plus I2C bus
  • Hardware address pin allows two devices on the same I2C, SMBus bus
  • Active-low reset input (RESET )
  • Open-drain active-low interrupt output (INT )
  • Input or output configuration register
  • Polarity inversion register
  • Configurable I/O drive strength register
