onsemi LC709004A
The LC709004A is a peripheral IC dedicated for expanding the capability of the microcontroller (MCU) I/O ports. It interfaces with the microcontroller through synchronous serial communication. The extended port features include the capabilities to specify the I/O direction on a bit basis, to specify the output type (CMOS or N-channel open drain), and to specify the I/O voltage level on a port basis according to the power level of the peripheral equipment.| Part No. | LC709004A |
