The MC74LVXT8053 utilizes silicon−gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. This analog multiplexer/demultiplexer controls analog voltages that may vary across the complete power supply range (from VCC to GND). The LVXT8053 is similar in pinout to the high−speed HC4053A, and the metal−gate MC14053B. The Channel−Select 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 Channel−Select and Enable inputs are compatible with TTL−type input thresholds. The input protection circuitry on this device allows overvoltage tolerance on the input, allowing the device to be used as a logic−level translator from 3.0 V CMOS logic to 5.0 V CMOS Logic or from 1.8 V CMOS logic to 3.0 V CMOS Logic while operating at the higher−voltage power supply. The MC74LVXT8053 input structure provides protection when voltages up to 7.0 V are applied, regardless of the supply voltage. This allows the MC74LVXT8053 to be used to interface 5.0 V circuits to 3.0 V circuits. This device has been designed so that the ON resistance (Ron) is more linear over input voltage than Ron of metal−gate CMOS analog switches.
