General Description

The TCA6416A is a 24-pin device that provides 16bits of 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 1.65 V to 5.5 V on the I2C bus side (VCCI) and a power supply voltage ranging from 1.65 V to 5.5 V on the P-port side (VCCP).

The device supports both 100-kHz (Standard-mode) and 400-kHz (Fast-mode) clock frequencies.

Overview

TCA6416A SCPS194F – MAY 2009 – REVISED JANUARY 2023 TCA6416A Low-Voltage 16-Bit I2C and SMBus I/O Expander With Voltage Translation, Interrupt Output, Reset Input, and Configuration Registers.

Key Features

  • I2C to parallel port expander.
  • 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, 2.5-V, 3.3-V, and 5-V I2C Bus and P-ports.
  • Low standby current consumption of 3 μA.
  • 5-V Tolerant I/O ports.
  • 400-kHz Fast I2C bus.
  • Hardware address pin allows two TCA6416A devices on the same I2C/SMBus bus.
  • Active-low reset input ( RESET).
  • Open-drain.
