IPC: G06F19/00
Filed: 1980-08-13
Abstract: PURPOSE:To decrease the number of pins of an integrated circuit, by transferring the signal between the digital and analog integrated circuits via a two-way signal line. CONSTITUTION:When a digital input signal (d) of a terminal 14 of a digital integrated circuit 1 is at L level, a signal output circuit is turned on. Then a signal  (e') of an input/output terminal 27 is set at H level. An input signal deciding circuit 12 is turned on, and an output signal (c') of a terminal 13 is set at L level. An  output (f') of a voltage comparator 32 is set at H level since the H-level signal (e')  of an input/ output terminal 30 of an analog integrated circuit 2 is set higher than  the comparison voltage (m) of the comparator 32. Then a signal (g) equal to an  analog input signal (a) of the terminal 3 is delivered via signal changeover circuits  20 and 23. When the signal (d) is set at H level, the circuit 15 is turned off. Then  the output voltage of an impedance converter 31 of a voltage comparator 5 is applied to the comparator 32. This voltage is lower than the voltage (m), so the signal (f') of the comparator 32 is set at L level to deliver the DC voltage (g) of a  certain level to the terminal 24. At the same time, a signal (c') having the same waveform as the output voltage of the converter is delivered to the terminal 13 via  the circuit 12.
