Digital signal switching circuit.

摘要

In a pushpull switching circuit, whose output transistors are controlled by complementary control signals, that one of the gate electrodes which carries a sec low sec signal is kept just at the threshold voltage of the output transistor to be cut off by means of a transistor (substantially) identical to the output transistors, the gate electrode and the main electrode (drain) of this transistor being interconnected. The junction (of this gate and this drain) is connected to sources (main electrodes) of two cross-coupled with gate and drain transistors, which are connected by their drain to the gate electrodes of the respective output reansistors.
