TEXAS INSTRUMENTS PCA9555DB 输入/输出扩展, 16bit, 400 kHz, I2C, SMBus, 2.3 V, 5.5 V, SSOP
The is a 16-bit I/O Expander for the two-line bidirectional bus I²C is designed for 2.3 to 5.5V VCC operation. It provides general-purpose remote I/O expansion for most microcontroller families via the I²C interface [serial clock SCL, serial data SDA]. The PCA9555 consists of two 8-bit configuration input or output selection, input port, output port and polarity inversion active high or active low operation registers. At power on, the I/Os are configured as inputs. The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding Input or Output register. The polarity of the input port register can be inverted with the Polarity Inversion register. The device outputs latched have high-current drive capability for directly driving LEDs. All registers can be read by the system master.
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
