MM74HC4066 Quad Analog Switch
Quad Analog Switch (74HC4066D) : IC42
General Description
The MM74HC4066 devices are digitally controlled analog
switches utilizing advanced silicon-gate CMOS technology.
These switches have low “ON” resistance and low “OFF”
leakages. They are bidirectional switches, thus any analog
input may be used as an output and visa-versa. Also the
MM74HC4066 switches contain linearization circuitry
which lowers the “ON” resistance and increases switch lin-
earity. The MM74HC4066 devices allow control of up to
12V (peak) analog signals with digital control signals of the
same range. Each switch has its own control input which
disables each switch when LOW. All analog inputs and out-
puts and digital inputs are protected from electrostatic
damage by diodes to V
CC
and ground.
Features
■ Typical switch enable time: 15 ns
■ Wide analog input voltage range: 0–12V
■ Low “ON” resistance: 30 typ. (MM74HC4066)
■ Low quiescent current: 80 µA maximum (74HC)
■ Matched switch characteristics
■ Individual switch controls
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
