Texas PCF8575PWR Remote 16-bit I/O expander for I2C-bus TSSOP. Pack of 10pcs

Information from the TI datasheet:

This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 2.5-V to 5.5-V 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/O's are high. In this mode, only a current source to VCC is active.

Price is for a pack of 10pcs, 3 packs are available.
