PCA9570
Overview
The PCA9570 is a CMOS device that provides 4 bits of General Purpose parallel Output (GPO) expansion in low voltage processor and handheld battery powered mobile applications. It operates at 1 MHz I2C-bus speeds while maintaining backward compatibility to Fast-mode (400 kHz) and Standard-mode (100 kHz).
- Features and benefits
- 1 MHz I2C-bus interface with 6 mA SDA sink capability for lightly loaded buses (<100 pF) and improved power consumption
- Compliant with the I2C-bus Fast and Standard modes
- 1.1 V to 3.6 V operation
- Latched outputs with a sink/source capability of 4 mA at 3.3 V
- Readable device ID (manufacturer, device type, and revision)
- Software Reset
- Power-On Reset
- Low standby current
- -40 °C to +85 °C operation
