Description
The Harris CD74HC4067 and CD74HCT4067 are digitally
controlled analog switches which utilize silicon-gate CMOS
technology to achieve operating speeds similar to LSTTL
with the low power consumption of standard CMOS
integrated circuits.
These analog multiplexers/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 visa-versa. The switches
have low “on” resistance and low “off” leakages. In addition,
these devices have an enable control which when high will
disable all switches to their “off” state.
