The LVXT8053 is similar in pinout to the highspeed HC4053A, and the metalgate MC14053B. The ChannelSelect inputs determine which one of the Analog Inputs/Outputs is to be connected by means of an analog switch to the Common Output/Input. When the Enable pin is HIGH, all analog switches are turned off. The ChannelSelect and Enable inputs are compatible with TTLtype input thresholds. The input protection circuitry on this device allows overvoltage tolerance on the input, allowing the device to be used as a logiclevel translator from 3.0V CMOS logic to 5.0V CMOS Logic or from 1.8V CMOS logic to 3.0V CMOS Logic while operating at the highervoltage power supply. The MC74LVXT8053 input structure provides protection when voltages up to 7V are applied, regardless of the supply voltage. This allows the MC74LVXT8053 to be used to interface 5V circuits to 3V circuits. This device has been designed so that the ON resistance (Ron) is more linear over input voltage than Ron of metalgate CMOS analog switches.
