SN74LVC165A: 是否具有bus hold

针对 Slow or Floating CMOS Inputs,根据scba004e p7,lvc内置bus hold,已经解决了 Slow or Floating CMOS Inputs

但根据 SN74LVC165A datasheet,又有input transition rise or fall rate的限制

到底如何解决该问题..

因为我前级的是RC滤波,因此信号是100us上升沿信号.

LVC 设备没有总线保持功能。LVCH 和 ALVCH 设备有总线保持功能。如果您需要总线保持功能，可以使用SN74ALVCH16244
