Voltage Level Translator

 Basic voltage Level Translator utilizes a voltage Comparator to translate an input voltage range into an output
voltage range. First step is to determine the input voltage range, which involves an input low voltage level
VIN(low) and an input high voltage level, VIN(high). Next step is to figure out the proper reference voltage
level, at VREF. In many cases VREF CAN be simply midpoint between VIN (low) and VIN(high). In other cases,
one may want to skew the VREF voltage level towards either VIN(low) or VIN(high). In this example, the output
voltage range is simple ground and V+, which also represent output voltage that range from rail to rail. For
logic circuit type of voltage Level Translator VREF could be set to 1.4V for TTL Logic voltages, and V+/2 for
CMOS Logic voltages.
