High-Performance Silicon-Gate CMOS The MC74LVX4066 utilizes silicon-gate CMOS technology to achieve fast propagation delays low ON resistances and low OFF-channel leakage current. This bilateral switch/multiplexer/demultiplexer controls analog and digital voltages that may vary across the full power-supply range (from VCC to GND). The LVX4066 is identical in pinout to the metal-gate CMOS MC14066and the high-speed CMOS HC4066A. Each device has four independent switches. The device has been designed so that the ON resistances(RON) are much more linear over input voltage than RON of metal-gate CMOS analog switches. The ON/OFF control inputs are compatible with standard CMOSoutputs; with pull-up resistors they are compatible with LSTTL outputs.
