Abstract

PURPOSE:To avoid the difference between the leading and trailing time at the capacitive load, by inserting a resistor between the transistor lower in output impedance and the output terminal. CONSTITUTION:The emitter of the output transistor 10 is directly connected to the output terminal 15, and the collector is connected to the power supply terminal 15 via the resistor 5. The resistor 6 is to correct the difference in the output impedance at the output signal leading of the driving circuit 16, at H level of the driving circuit output, and at the L level of output, and since the outut impedance of the third is lower, it is inserted between the output terminal 15 and the transistor 11.
