The Texas Instruments TCA6424A is a 24-bit I/O expander designed for general-purpose remote I/O expansion via the I2C interface. It supports a wide operating power-supply voltage range from 1.65 V to 5.5 V, enabling it to interface with microcontrollers and microprocessors that use lower supply levels.
This device allows for bidirectional voltage-level translation and GPIO expansion between various SCL/SDA and P port voltages, including 1.8V, 2.5V, 3.3V, and 5V. It features a 400-kHz fast I2C bus, a low standby current consumption of 1 µA, and 5-V tolerant I/O ports. The TCA6424A includes an active-low reset input and an open-drain active-low interrupt output.
Key features include Schmitt-trigger action for improved noise immunity on SCL/SDA inputs, input/output configuration registers, and polarity inversion registers. The latched outputs offer high-current drive capability, suitable for directly driving LEDs. The device is provided in a 32-pin UQFN package with a body size of 5.00 mm x 5.00 mm.
