LTC6994 - TimerBlox：延迟模块 / 防反跳器
LTC®6994 是一款可编程延迟模块，具有一个 1μs 至 33.6s 的延迟范围。LTC6994 隶属于 TimerBlox® 通用型硅定时器件系列。
单个电阻器 RSET 编程一个内部主振荡器频率，从而设置 LTC6994 的时基。输入至输出延迟由该主振荡器和一个内部时钟分频器 NDIV 来决定 (可编程至 1 ~ 221 范围内的 8 个设定值) :
在延迟了上升和 / 或下降变换之后，输出 (OUT) 将跟随输入 (IN)。LTC6994-1 将延迟上升沿或下降沿。LTC6994-2 将延迟上升及下降变换，并增添了用于使输出反相的选项。
LTC6994 还具备通过一个单独的控制电压来动态地调节延迟时间的能力。
