The MC74LVXT4051 utilizes silicon-gate CMOS technology to achieve fast propagation delays, low ON resistances, and low leakage currents. This analog multiplexer/demultiplexer controls analog voltages that may vary across the complete power supply range (from V to V ).The LVXT4051 is similar in pinout to the LVX8051, the HC4051A, and the metal-gate MC14051B. 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 standard TTL levels. These inputs are over-voltage tolerant (OVT) for level translation from 6.0 V down to 3.0 V. This device has been designed so the ON resistance (R ) is more linear over input voltage than the R of metal-gate CMOS analog switches and High-Speed CMOS analog switches.
