Dear supporters,
1. What is SN74ALVCH374 CLK voltage level? 3.3V or else?
2. Could you help to explain principle about "internal flip-flop"?
I can't find how to work in spec.
Thanks.
您好,
1. What is SN74ALVCH374 CLK voltage level? 3.3V or else?
与供电电压有关,如下截图定义:
2. Could you help to explain principle about "internal flip-flop"?
今天来不及了,下周我将具体看下这个问题,若对您造成不便很抱歉
很抱歉现在才回复您的问题。
SN74ALVCH374是D型触发器,OE是其使能管脚,CLK是其输入时钟,D是其数据输入,Q是其数据输出;使能管脚OE低电平有效,高电平时输出Q为高组态;OE低电平时,当有CLK上升沿时,输出数据Q=D,在CLK的其他状态,输出数据Q保持不变。
如果您需要SN74ALVCH374的具体内部电路,很抱歉这部分信息TI不公开。
