Intersil CDP68HC68P1
The CDP68HC68P1 is a serially addressed 8-bit Input/Output port that allows byte or individual bit control. It consists of three registers, an output buffer and control logic. The I/O port data flow is controlled by the Data Direction Register and data is stored in the Data Register that outputs or senses the logic levels at the buffered I/O pins.| Part No. | CDP68HC68P1 |
