描述 Description

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 VCC to VEE ). 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 (Ron ) is more linear over input voltage than Ron of metal-gate CMOS analog switches, and High-Speed CMOS analog switches.
