Title: Current switching circuit
Inventor: MAIKERU SARIBU MIKEERU
IPC: H03K19/086
Filed: 1988-11-17
Abstract: PURPOSE: To prevent a switching error by respectively providing one input terminal, input transistor, 1st reference power source, transistor load resistor, 2nd reference power source, constant resistor between transistors, and means of feedback to an input transistor main current. CONSTITUTION: When one of transistors 16, 22 and 24 is turned on, a current flows from a 1st reference power source 26 to a load resistor 28, a voltage at a terminal 18 is dropped, a pnp transistor 36 at a feedback means 34 is turned on, and a constant resistor 32 is electrified through a terminal 20. When a voltage 'H' at input terminals 10, 12 and 14 of input transistors 16, 22 and 24 in ON state is fluctuated, the pnp transistor 36 suppresses the fluctuation of VBE at the input transistor through the resistor 32 by supplying a feedback current to the resistor 32 and prevents the voltage fluctuation at a terminal 40 by letting a constant main current flow to the load resistor 28. A capacitor 54 is connected to the emitter of the input transistor and speed-up is attained.  Thus, even when a noise is inputted to the input terminal, that is not transmitted to a switching circuit provided with a transistor 46 so that no operation error can occur.
