The MC54/74HC4066A utilizes silicongate 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 powersupply range (from VCC to GND). The HC4066A is identical in pinout to the metalgate CMOS MC14016 and MC14066. 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 metalgate CMOS analog switches. The ON/OFF control inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. For analog switches with voltagelevel translators, see the HC4316A.
