To prevent latching of the bidirectional channels, the input logic-low threshold (VIT) of I/OA1 and I/ OA2 is at least 50mV lower than the output logic-low voltages (VOL) of I/OA1 and I/OA2. This prevents an output logic-low on side A from being accepted as an input low and subsequently ...

Buck converter
A buck converter is a voltage step down and current step up converter.The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
