The PCF8575DBR is a high-quality, advanced technology product from Texas Instruments, a leading global semiconductor company renowned for its innovative and reliable products.

• Function: 16-bit I/O expander that provides remote I/O expansion for most microcontroller families through the I2C interface serial link.
• Feature: General-purpose remote I/O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)).
• Feature: 16-bit quasi-bidirectional input/output (I/O) port (P07..P00, P17..P10), including latched outputs with high current drive capability for directly driving LEDs.
• Feature: Has an interrupt output, which can be connected to the interrupt logic of the microcontroller.
• Advantage: Low standby current consumption.
• Temperature Range: Operates over an ambient temperature range from -40 °C to +85 °C.
• Package: Available in a small-outline package (SO16) and TSSOP (TSSOP24).
• Compliance: RoHS compliant.
