TCA6416A I²C and SMBus I/O Expander

Texas Instruments' low-voltage 16-Bit I²C and SMBus I/O expander

Image of Texas Instruments' TCA6416A I²C and SMBus I/O Expander Texas Instruments' 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)]. The major benefit of this device is its wide VCC range. It can operate from 1.65 V to 5.5 V on the P-port side and on the SDA/SCL side. This allows the TCA6416AA to interface with next-generation microprocessors and microcontrollers on the SDA/SCL side, where supply levels are dropping down to conserve power.

Features
  • Operating power-supply voltage range of 1.65 V to 5.5 V
  • I2C to parallel port expander
  • Low standby current consumption of 3 µA
  • Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs
Applications
  • Cell phones
  • PDAs
  • Portable media players
  • MP3 players
  • Portable instrumentation
