TCA6416 - Low-Voltage 16-Bit I2C and SMBus I/O Expander

General Description

This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed to provide general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL) and serial data (SDA)].

Key Features

  • 1 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.
