I/o Expanders datasheet and documents for PCA9570GMH

PCA9570GMH

I/o Expanders Overview

The PCA9570GMH is a CMOS device providing 4-bit General Purpose parallel Output (GPO) expansion. It operates at 1 MHz I2C-bus speeds while maintaining backward compatibility to Fast-mode (400 kHz) and Standard-mode (100 kHz). The device features latched outputs with symmetrical 4 mA current drive capability at 3.3 V. It operates within a low voltage range of 1.1 V to 3.6 V and includes an internal Power-On Reset (POR) and Software Reset feature. The component is housed in an XQFN8 package measuring 1.6 x 1.6 x 0.5 mm.
