The MC74LVX4051 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 LVX4051 is similar in pinout to the LVX8051, 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 CMOS outputs. These inputs are over-voltage tolerant (OVT) forlevel 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 R
of metal-gate CMOS analog switches, and High-Speed CMOS analog switches.
