description/ordering information

This 8-bit input/output (I/O) expander for the two-line bidirectional bus (I C) is designed for 2.5-V to 6-V V  
operation.  
CC  
2
The PCF8574 provides general-purpose remote I/O expansion for most microcontroller families via the I C  
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  
V
is active. An additional strong pullup to V  
allows fast rising edges into heavily loaded outputs. This device  
CC  
CC  
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.
