DESCRIPTION/ORDERING INFORMATION  
This 8-bit input/output (I/O) expander for the two-line bidirectional bus (I2C) is designed for 2.5-V to 6-V VCC  
operation.  
The PCF8574 provides general-purpose remote I/O expansion for most microcontroller families via the I2C  
interface [serial clock (SCL), serial data (SDA)].  
The device features an 8-bit quasi-bidirectional I/O port (P0–P7), including latched outputs with high-current drive  
capability for directly driving LEDs. Each quasi-bidirectional I/O can be used as an input or output without the use  
of a data-direction control signal. At power on, the I/Os are high. In this mode, only a current source to VCC is  
active. An additional strong pullup to VCC allows fast rising edges into heavily loaded outputs. This device turns  
on when an output is written high and is switched off by the negative edge of SCL. The I/Os should be high  
before being used as inputs.
