tri-state buffer 1 Articles . Better SPI Bus Design. November 25, ... Putting a pullup on the CS lines keeps everything at the right logic level until a device is actually needed.

Engineers in the trenches generally take the position that an active-high state is one whose active state is considered to be True or logic 1, while an active-low state is one whose active state is ...

Tri-state buffers offer low ASIC area and leakage power in the range of approximately one third of the figures for comparable multiplexers with sequential select signal encoding. The latency of a ...

tri-state 2 Articles . ... just connect two resistors so the MISO line floats to a non-logic level when the CS pin is high, ... you should put a small tri-state buffer in there.
