SCHALTUNG ZUM UMSETZEN VON DREI-ZUSTANDS-SIGNALEN IN BINAERE SIGNALE.

摘要

Two d.c. sources (S1,2) are respectively connected to a negative and positive terminal of a supply voltage source. The d.c. sources are coupled to an output transistor (Tp,Tn) via two diode paths (D1,2) with a common input (I), and via further two diode paths (D3,4) of identical type, the coupling providing two output signals. Of the third and fourth diode path, one is pref. coupled directly to the respective output transistor, while the other is coupled via a current mirror, with the two output transistors in identical connections. To the input of at least one output transistor may be parallel-connected a switching transistor controllable by the current mirror output current.
