产品概述
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 device provides general-purpose remote I/O expansion for most microcontroller
families by way of 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.
