The LVXT4053 is similar in pinout to the LVX8053, the 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 standard TTL levels.
