PCF8575RGER Description

Short technical summary and product information.

The Texas Instruments PCF8575RGER is a 16-bit general-purpose remote I/O expander that communicates via the I2C/SMBus interface. It is designed for VCC operation from 2.5V to 5.5V, making it compatible with a wide range of microcontrollers.

 

This device offers a 16-bit quasi-bidirectional I/O port with latched outputs capable of directly driving LEDs. It supports a fast 400kHz I2C bus speed and allows for addressing up to eight devices using three hardware address pins. The PCF8575RGER includes an open-drain interrupt output, which is useful for signaling external events.

 

Packaged in a 24-VQFN (4x4) form factor, the PCF8575RGER is suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C. The part is supplied in a large tape and reel package with a standard quantity of 3,000 units.

 

Key electrical characteristics include a low standby current consumption of a maximum of 10µA. The outputs feature high-current drive capability and can actively drive a high at the output. Latch-up performance exceeds 100mA per JESD 78, class II, and ESD protection exceeds JESD 22 standards.
