NXP PCA9570 4-Bit General Parallel Output

NXP PCA9570 4-Bit General Parallel Output Expander

NXP PCA9570 4-Bit General Parallel Output (GPO) Expander is a remote CMOS device designed for 4-bit general purpose parallel output (GPO) expansion in low voltage processor and handheld battery powered mobile applications. PCA9570 achieves 1 MHz I2C-bus speeds while maintaining backward compatibility to Fast-mode (400 kHz) and Standard-mode (100 kHz). The streamlined design consists of 4-bit push-pull outputs that provide low current consumption, small packaging options and a low operating voltage range of 1.1 V to 3.6 V. Latched outputs are symmetrical 4 mA current drive capability at 3.3 V to drive various control logic. The PCA9570 output expander offers a simple solution when additional outputs are needed while keeping interconnections and floor space to a minimum.
