PCF8575PWRE4

PCF8575PWRE4 is a versatile IO expander device with an integrated I2C interface. It is mostly used in industrial automation, data acquisition, medical, building systems and other areas. This device offers a 16-bit I/O port with a register based design that can be used to control a wide range of IO peripherals. The PCF8575PWRE4 is available in a variety of packages with various product features, such as programmable I/O ports, automatic input/output port status update, buffered input/output port, easy and reliable connection of multiple devices, locking of the device and low power dissipation.

This device is designed for use in 8 or 16 bit microprocessor systems, where a reduced number of ports is needed. It can be used to expand the number of available ports, control multiple devices, or interface multiple I2C devices to the same bus. PCF8575PWRE4 can be used in a variety of applications such as industrial automation, security systems and power management.

PCF8575PWRE4 offers an 8-bit I2C bus interface, which is used to address up to 16 CMOS inputs or outputs. Data output is realized automatically when reading from the device\'s register and writing to the register causes data output. All 16 bits of the port can be accessed as a single 8-bit port or can be read or written as individual bits. The device also offers a buffered input and output port line, which can be used to reduce the number of necessary I2C bus transactions when interfacing multiple devices.

The PCF8575PWRE4 is powered by an integrated low-power 5V regulator. The device supports I2C protocol speeds of up to 400 kHz and can be suspended via the external suspend pin. The device also has a locking feature which allows the application to be locked in a specific state so that it cannot be changed without an external reset. This feature also provides protection against accidental change of settings.

PCF8575PWRE4 is ideal for applications where multiple I2C-controlled IO devices need to be connected and where low power consumption is important. The device is available in a variety of packages, including a 32-pin TQFP, a 28-pin DIP and a 16-pin SSOP packages.
