Filed: 1975-04-10
Abstract: 1494234 Transistor logic and current mirror circuits; automatic exchange systems RCA CORPORATION 10 April 1975 [24 April 1974] 14741/75 Headings H3T and H4K [Also in Division H1] An OR gate comprises a plurality of transistors 112, 122, 132, 142 having their output terminals connected to a common output and their common terminals direct coupled to a reference (ground), a respective resistor 111, 121, 131, 141 connected between the input of each transistor and the reference and at least one current regulator 105 coupled to each of the input terminals and arranged to sense the currents in the common electrodes so as to counteract a tendency of the combined common electrode currents to be larger than a predetermined value, irrespective of the number of input signals applied to said plurality of transistors 112, 122, 132, 142. As shown in Fig. 3, the invention is applied to a cross-point switching system for a telephone exchange and used to prevent the simultaneous conduction of any row. SCR's 151, 161, 171, 181 form part of one row of the cross-point switch. The currents in the SCR's are monitored by means of auxiliary floating electrodes connected to transistors 154... 184 and are applied to the inputs of the transistors 112... 142 of the OR gate. These transistors are preferably coupled to a common emitter resistor 103 by means of a Darlington transistor 106 and have a common current regulating transistor 105 which is coupled via isolating diodes 113... 143 back to their inputs so as to minimize the maximum current in transistor 106. If any of SCR's 151... 185 is conductive, the signal at the collector of transistor 106 will be such as to turn on transistors 201, 202 which will prevent triggering of any of the SCR's. In Fig. 1 (not shown) transistor 106 is omitted and a separate current regulating transistor 105 provided for each input transistor 112... 142. FET's are envisaged. Current mirror switching.-If none of the SCR's 151... 181 is conductive, a COMMAND INPUT at 211 will turn on transistors 214, 216 so that the collector current will be determined by resistor 215 and will be fed to transistors 221, 223 the former being in a degenerative feedback path around the latter so that a controlled current will be fed to transistors 225... 228 and hence to transistors 235... 238 which are coupled via respective diodes 245 ... 248 to the gates of the row SCR's 151... 181 so as to turn on whichever SCR has its anode/cathode forward biased. Integrated circuits.-Figs. 4-6 (see Division H1) depict integrated construction of transistor 105, resistors 111... 141 and diodes 113... 143: diodes 245 ... 248 are formed as lateral transistors.
