PCA9571GUX Description

Short technical summary and product information.

The PCA9571GUX is an 8-bit general-purpose parallel output (GPO) expander designed by NXP Semiconductors for low-voltage applications. It utilizes a 1 MHz I2C-bus interface, backward compatible with Fast-mode (400 kHz) and Standard-mode (100 kHz).

 

This device operates within a voltage range of 1.1 V to 3.6 V and features 8 push-pull outputs with a symmetrical 4 mA current drive capability at 3.3 V. It includes Power-On Reset (POR) and Software Reset features for initialization. The PCA9571GUX is suitable for applications requiring additional outputs in space-constrained, battery-powered mobile devices.

 

The PCA9571GUX comes in a compact 12-XQFN surface-mount package. It operates across a temperature range of -40 °C to +85 °C, with ESD protection exceeding 2000 V HBM. The device is compliant with RoHS3 standards.
