Abstract

본 발명은 두 직렬력을 하나의 출력단에서 수신하여 처리하는 것에 관한 것으로서, 두 직렬 입력중 하나의 입력에 우선 순위를 주어 타 입력에 관계없이 출력단으로 우선적으로 선택되어 수신될 수 있도록 하는 두 직렬 입력 충돌 방지회로에 관한 것이다.The present invention relates to receiving and processing two serial forces at one output stage, wherein two serial inputs are given priority to one of the two serial inputs so that they can be preferentially selected and received at the output stage regardless of the other inputs. It relates to a collision avoidance circuit.

종래에는 다수의 입력신호에 따라 후단의 구동을 제어하는 마이콤이나 제어수단에 입력되는 다수의 입력신호중 임의의 입력신호를 우선적으로 선택하여 처리하는 구성이 없었다.Conventionally, there is no configuration for preferentially selecting and processing any input signal among a plurality of input signals input to a microcomputer or a control means for controlling the driving of the rear stage according to a plurality of input signals.

따라서 본 발명은 이를 개선하기 위하여 제1도에서와 같이 입력단(TX2)을 통한 입력신호에 의해 구동하는 트랜지스터(Q1)(Q3)를 구성하고 입력단(TX1)의 입력신호에 의해 상기 트랜지스터(Q1)(Q3)가 구동이 정지하고 트랜지서터(Q2)만이 구동되도록 구성한 것이다.Thus, the present invention is said by the input signal of the transistor (Q 1) (TX 1) (Q 3) the configuration and input driven by an input signal through the input terminal (TX 2), as shown in FIG. 1 in order to improve this, The transistor Q 1 and Q 3 are configured such that the driving stops and only the transistor Q 2 is driven.
