Claims

[Scope of utility model registration request]

(1) A memory circuit that stores digital signal data to be exchanged with an electronic computer; and a memory circuit that is connected to the memory circuit via data wiring for the digital signal and that mutually exchanges the digital signal and analog signal. a conversion circuit that converts the analog signal into a digital signal; an insulated amplifier circuit that transmits and receives the analog signal between the conversion circuit; and a signal interposed in the data wiring that transmits the most significant bit of the digital signal among the data wiring. An electronic computer input/output device comprising an inverting circuit.

(2) The computer input/output device according to claim 1, wherein the conversion circuit is a digital-to-analog conversion circuit, and the input/output device also functions as an analog signal output.

(3) The computer input/output device according to claim 1, wherein the conversion circuit is an analog-to-digital conversion circuit, and the input/output device functions as an analog signal input device.
