TCA6424ARGJR

Расширитель I/O, 24бита, 400 кГц, I2C, SMBus, 1.65 В, 5.5 В, UQFN.

The TCA6424ARGJR is a low-voltage 24-bit I?C and SMBus I/O Expander designed to provide general-purpose remote I/O expansion for most microcontroller families via the I?C 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.
