Figure 7 shows a complete timing diagram for the AD574A convert start operation. R/C should be low before both CE and CS are asserted; if R/C is high, a read operation will momentarily occur, possibly resulting in system bus contention. Either CE or CS may be used to initiate a conversion; however, use of CE is recommended since it includes one less propagation delay than CS and is the faster input. In Figure 7, CE is used to initiate the conversion.

图7显示的是完整的AD574A运作时间矢量图表.坐标轴R/C在CE和CS被捕获之前都应较低;如果R/C显示较高,操作提示会立即发生,并可能引发系统争用.无论CE还是CS都能被用来转换.但是,我们推荐使用CE,因为它比CS有更少的系统延迟,并且能被较快地输入.在图表7,CE被用来转换.

为西元 574A 皈依者开始行动的图 7 表演一个完全的时间安排图表。 在 CE 和 CS 被断言之前, R/C 应该是低的; 如果 R/C 是高的,阅读操作暂时地将会发生,可能地造成系统公共汽车争论。 CE 或 CS 可能用来开始转变; 然而,因为它包括, CE 的使用被推荐一不是增殖延迟而是 CS 和是较快速的输入。 在图 7 中, CE 用来开始转变。
