PCA9670PW,118 Description

Short technical summary and product information.

The PCA9670PW,118 from NXP Semiconductors is an 8-bit remote I/O expander designed for the I2C-bus. It provides general-purpose I/O expansion through a two-wire bidirectional I2C-bus interface, supporting Fast-mode Plus I2C-bus at up to 1 MHz. This device features eight quasi-bidirectional ports that can be independently configured as inputs or outputs. The latched output ports offer a 25 mA high current sink drive capability, suitable for directly driving LEDs.

 

Operating between 2.3 V and 5.5 V, the PCA9670PW,118 includes features such as Power-On Reset (POR) and an active LOW hardware reset pin. It supports up to 64 devices on the same I2C-bus, allowing for extensive I/O expansion. The device is housed in a 16-TSSOP package and operates within a temperature range of -40°C to +85°C.

 

Key specifications include an operating voltage range of 2.3V to 5.5V, a 1 MHz clock frequency, and 8 I/O pins. The interface is I2C, with an output type of Push-Pull. The typical static current consumption is low at 2.5 µA, making it suitable for mobile applications. The latched outputs can sink up to 25 mA, and the total package sink capability is 200 mA.
