  These signals violate the setup and hold times specified in section 7.6 of the datasheet. What is the purpose of using a flip-flop in this circuit? Why are you mentioning the '245 transceiver? It's possible that that device, or a transparent latch like…

  Hi Roy, The HC family of logic also has clamp diodes and will not resolve this issue. Perhaps an illustration will be of some help. Each transceiver device has both input and output structures connected to the pin. When you try to drive the output of…
