SCPS193C – JULY 2010 – REVISED APRIL 2014 TCA6424A Low-Voltage 24-Bit I2C and SMBus I/O Expander
With Interrupt Output, Reset, and Configuration Registers
1 Features 2 Description This 24-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)]. DEVICE NAME

Center Pad 23 Device Information(1) 24 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 TCA6424A
to interface with next-generation microprocessors and
microcontrollers on the SDA/SCL side, where supply …
