Title: Semiconductor switching device
Inventor: YAMAGUCHI SHUICHIRO
IPC: H03K17/78
Filed: 1986-12-11
Abstract: PURPOSE:To execute a high speed and exact operation by providing two light emitting elements, an inductance component, a field effect transistor, and two light electromotive force elements. CONSTITUTION:When an input current is allowed to flow between input terminals I1, I2, a light emitting element L1 generates an optical signal, by which a light electromotive force from a light electromotive force element P1 is impressed between a gate and a source of a field effect transistor TR Q. This light electromotive force is set higher than a threshold voltage of the TR Q, therefore, an impedance between a source and a drain of the TR Q becomes a low state, and a part between output terminals O1, O2 becomes an ON state. When the input current is cut off suddenly, the element L1 stops its light emission, a counter electromotive force is generated, and an element L2 emits a light beam instantaneously. By an element P2, an electromotive force in the direction reverse to the element P1 is generated, and inputted to a gate and a source of the TR Q. Therefore, the impedance between a source and a drain of the TR Q becomes quickly a high state, and the part between the terminals O1, O2 becomes quickly OFF. Accordingly, a high speed and exact operation can be executed.
