3 Description
The CD74HC4067 and CD74HCT4067 devices are
digitally controlled analog switches that use silicongate
CMOS technology to achieve operating speeds
similar to LSTTL, with the low power consumption of
standard CMOS integrated circuits.
These analog multiplexers and demultiplexers control
analog voltages that may vary across the voltage
supply range. They are bidirectional switches, thus
allowing any analog input to be used as an output and
vice-versa. The switches have low on resistance and
low off leakages. In addition, these devices have an
enable control that, when high, disables all switches
to their off state.
