PCF8575DBR

TEXAS INSTRUMENTS  PCF8575DBR  输入/输出扩展, 16bit, 400 kHz, I2C, SMBus, 2.5 V, 5.5 V, SSOP

The is a 16-bit I/O Expander for the two-line bidirectional bus I²C is designed for 2.5 to 5.5V VCC operation. The PCF8575 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 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. 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.
