Abstract
A single wire digital communication system for use with an ultrasonic surgical instrument and an ultrasonic surgical instrument including a single wire digital communication system. The single wire digital communication system includes first transmitter logic buffer and first receiver logic buffer operably coupled to a first single wire device via a first single wire communication bus. The single wire digital communication system also includes a first differential transceiver operational amplifier operably coupled to the first transmitter logic buffer via a first transmitter signal line and operably coupled to the first receiver logic buffer via a first receiver signal line. A second differential transceiver operational amplifier is operably coupled to the first differential transceiver operational amplifier via at least one differential bus. A second single wire device is operably coupled to the differential bus and configured to communicate with the first single wire device.
