Description
Claims (1)
- 단국 인에이블신호(Shelf1EN∼Shelf3EN)를 감지하여 우선 순위를 결정하는 오어게이트(OR1∼OR3)와, 상기 오어게이트(OR1∼OR3)출력신호를 반전시켜 후단의 노어게이트(NOR1∼NOR3)에 출력시키는 인버터(INV1∼INV3)와, 상기 오어게이트(OR1∼OR3)출력과 인터버(INV1∼INV3)출력을 노어링하는 노어게이트(NOR1∼NOR3)와, 상기 노어게이트(NOR1∼NOR3)출력과 전원(Vcc)을 논리곱하여 릴레이(RLY1∼RLY3)동작을 단속하는 앤드게이트(AND1∼AND3)와, 상기 앤드게이트(AND1∼AND3)의 출력상태에 따라 스피커 구동신호(SP1 +,-∼ SP3 +,-)를 공급 또는 차단하는 릴레이(RLY1∼RLY3)로 구성된 것을 특징으로 하는 공통랙 사용 단국(SHELF)호출시 스피커 구동장치.
