PCF8575 REMOTE 16-BIT I2C AND SMBus I/O EXPANDER WITH INTERRUPT OUTPUT www.ti.com SCPS121D – JANUARY 2005 – REVISED APRIL 2007 DESCRIPTION/ORDERING INFORMATION (CONTINUED) The PCF8575 provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface serial clock (SCL) and serial data (SDA). The device features a 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.
