据报道,Siliconix公司采用CMOS工艺,研制成功一台8个输入的模拟多路传输样机,该机能大大减少微处理机总线与控制、测试模拟系统间的接口。多路传输机的内寄存器使接口直接进行编程,或以8个输入的每一个输入进行编程,或以整个部件进行编程。当WR输入位于低电平时,寄存器是透明的(写入启动);此时,模拟多路传输机通过对A_2,A_1和A_0的直接控制进行工作。当接通电源,RS再启动输入就有效,并
According to reports, Siliconix companies using CMOS technology, the successful development of a 8-input analog multiplexer prototype, which can greatly reduce the microprocessor bus and control, test the interface between simulation systems. The multiplexer's internal registers allow the interface to be programmed directly, or programmed for each of the eight inputs, or programmed for the entire part. When the WR input is low, the register is transparent (write enabled); at this point, the analog multiplexer is operated with direct control of A_2, A_1 and A_0. When the power is turned on, the RS restart input is valid, and
