I am working with 80c196kc; I have connect 7 to 8 chips to the address and data bus of the microcontroller, including two RAMS(AS7c256) and 6 latches(74hc373).
Question is, should i be using a buffer(74hc245).
Moreover as a rule of thumb how many chips can be safely connected to a buffer/tranceiver.
I have tried using datasheets; the datasheet of latch(74hc373 ) shows a max input current of 20ma and upto 10uA of input leakage current. Whereas the output current of buffer(74hc245) is 20mA. Now i know i cant use the max input current of latch but can i use the leakage current. I am preplexed. Therefore a rule of thumb will be more than welcome.
