    • A magazine (1) for a plurality of disc-shaped information carriers (50) contained in holders (7) situated one above the other, comprising an opening (8,9) near at least one upright side for the insertion and removal of the holders (7). A pivotable latching lever (12;55) is arranged near one of the side walls (3), which lever comprises two arms, of which one arm carries a latching element (13, 14; 56, 57) near said opening and the other arm can be actuated from the exterior of the magazine to pivot the latching lever (12; 55) from a first position to a second position against the force of spring means (16), in which second position the holders (7) of the latching element (13, 14; 56, 57) are released, so that the holders (7) can be slid through the opening (8, 9).

    • A switching circuit comprises a pre-stage circuit coupled to receive an input signal and an output stage, wherein an output signal having a phase opposite to that of a signal of an input terminal IN can be obtained from an output terminal OUT of the output stage. The pre-stage circuit includes a p-channel MOSFET M1 and an n-channel MOSFET M2 that receive input signals at their gates. The output stage includes two NPN transistors Q1 and Q2 that are connected in series. The drain output of the p-channel MOSFET M1 is applied to the base of one of the transistors of the output stage, and the source output of the n-channel MOSFET M2 is applied to the base of the other of the transistors of the output stage. A third MOSFET M3 is coupled between a power supply and the p-channel MOSFET M1 and the n-channel MOSFET M2. When the MOSFET M3 is rendered non-conductive by a control signal EN, both MOSFETs M1 and M2 and both NPN transistors Q1 and Q2 become non-conductive irrespective of the signal of the input terminal IN. Under this condition, the output terminal OUT is in a floating state. Thus, the switching circuit is a tri-state circuit.
    • 开关电路包括耦合以接收输入信号的预级电路和输出级,其中可以从输出级的输出端OUT获得具有与输入端IN的信号相反的相位的输出信号 。 该前级电路包括在其栅极接收输入信号的p沟道MOSFET M1和n沟道MOSFET M2。 输出级包括串联连接的两个NPN晶体管Q1和Q2。 p沟道MOSFET M1的漏极输出被施加到输出级的一个晶体管的基极,并且n沟道MOSFET M2的源极输出被施加到输出的晶体管的另一个的基极 阶段。 第三个MOSFET M3耦合在电源和p沟道MOSFET M1和n沟道MOSFET M2之间。 当通过控制信号EN使MOSFET M3不导通时,无论输入端子IN的信号如何,MOSFET M1和M2以及两个NPN晶体管Q1和Q2都不导通。 在这种情况下,输出端子OUT处于浮置状态。 因此,开关电路是三态电路。
