Product Overview

The TCA6424ARGJR is a low-voltage 24-bit I²C and SMBus I/O Expander 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 on the P-port side and on the SDA/SCL side. This allows the TCA6424A to interface with next-generation microprocessors and microcontrollers on the SDA/SCL side, where supply levels are dropping down to conserve power. In contrast to the dropping power supplies of microprocessors and microcontrollers, some PCB components, such as LEDs, remain at a 5V power supply.
  • I²C to parallel port expander
  • Allows bidirectional voltage-level translation and GPIO expansion
  • Low standby current consumption
  • Active-low reset input
  • Open-drain active-low interrupt output
  • Input/output configuration register
  • Polarity inversion register
  • Internal power-on reset
  • Green product and no Sb/Br
This IC can be damaged by ESD. We recommend that all ICs be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
