Product details

Description

The PCA9574 is a CMOS device that provides 8 bits of General Purpose parallel Input/Output (GPIO) expansion in low voltage processor and handheld battery powered mobile applications and was developed to enhance the NXP family of I2C-bus I/O expanders.

Features

400 kHz I2C-bus serial interface NXP Semiconductors PCA9574 8-bit I2C-bus and SMBus, level translating, low voltage GPIO with reset and interrupt.
Compliant with I2C-bus Standard-mode (100 kHz).
Separate supply rails for core logic and I/O bank provides voltage level shifting.
1.1 V to 3.6 V operation with level shifting feature.
Very low standby current: < 1 μA.
8 configurable I/O pins that default to inputs at power-up.
Output.
