HI,
SN74CB3Q3345 datasheet contains content below: "Rail-to-Rail Switching on Data I/O Ports".
Does it mean, the output Voltage Level is the same as the input, regadless of the Vcc supply?
For example, the Vcc supply is 3.3V, input signal Voltage Level is 1.8V, then the output Voltage Level
is also 1.8V? Or, the output level follows the Vcc, is 3.3V?
