SN74LVC74A双正极触发d型触发器设计用于2.7 v至3.6 v的VCC工作。
预设(PRE)或清除(CLR)输入端的低电平设置或重置输出,而不考虑其他输入的电平。当PRE和CLR处于非活动状态(高)时,满足设置时间要求的数据(D)输入端的数据被传输到时钟脉冲正沿的输出端。时钟触发发生在电压水平上,与时钟脉冲的上升时间没有直接关系。在保持时间间隔之后,可以改变D输入端的数据,而不影响输出端的电平。
输入可以从3.3 V或5 V设备驱动。该特性允许在混合3.3 V/5 V系统环境中使用该设备作为转换器。

(1)Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This includes, but is not limited to, Highly 一个ccelerated Stress Test (H一个ST) or biased 85/85, temperature cycle, autoclave or unbiased H一个ST, electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits.
