术语 | interface latch chip |
释义 | interface latch chip 接口锁存器芯片 A latch chip for interfacing which can be used as a bidirectional input/output port, a dedicated input port, or as a dedicated output port. A control signal (dynamic for bidirectional mode and static for dedicated modes) is supplied by the user in many cases. Separate control lines enable the input/output ports; thus, the latch may be a highimpedance device, i.e., it does not load the system bus unless an enable signal is present. 一种用作接口的锁存器芯片,可用作双向输入输出端口、专用输入端口或专用输出端口。 在许多情况下,由用户提供一种控制信号(对双向方式是动态的,对专用方式是静态的)。 分离的控制线路能够启连输入输出端口,因此,锁存器可以是高阻抗的设备,即除出现启连 信号外,它不加载系统总线。 |
