Product details

Description

The PCA9575 is a CMOS device that provides 16 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

Separate supply rails for core logic and each of the two I/O banks provides voltage level shifting.
1.1 V to 3.6 V operation with level shifting feature.
Very low standby current: < 2 μA.
16 configurable I/O pins organized as 2 banks that default to inputs at power-up.
Outputs:.
Totem pole: 1 mA source and 3 mA sink.
Independently programmable 100 kΩ pull-up or pull-down for each I/O pin.
Open-drain active LOW interrupt (IN.
