MC74LVXT8053 Analog Multiplexer / Demultiplexer High–Performance Silicon–Gate CMOS 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 3.0V CMOS logic to 5.0V CMOS Logic or from 1.8V CMOS logic to 3.0V CMOS Logic while operating at the higher–voltage 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 metal–gate CMOS analog switches. http://onsemi.com 16–LEAD SOIC D SUFFIX CASE 751B 16–LEAD TSSOP DT SUFFIX CASE 948F PIN CONNECTION AND MARKING DIAGRAM……
