MC74VHC1GT66
Advance Information
Analog Switch
The MC74VHC1GT66 is an advanced high speed CMOS bilateral
analog switch fabricated with silicon gate CMOS technology. It
achieves high speed propagation delays and low ON resistances while
maintaining CMOS low power dissipation. This bilateral switch
controls analog and digital voltages that may vary across the full
power–supply range (from VCC to GND).
The MC74VHC1GT66 is compatible in function to a single gate of
the very High Speed CMOS MC74VHCT4066. The device has been
designed so that the ON resistances (RON) are much lower and more
linear over input voltage than RON of the metal–gate CMOS or High
Speed CMOS analog switches.
The ON/OFF Control input is compatible with TTL–type input
thresholds allowing the device to be used as a logic–level translator
from 3.0V CMOS logic to 5.0V CMOS logic or from 1.8V CMOS
logic to 3.0V CMOS logic while operating at the high–voltage power
supply. The input protection circuitry on this device allows
overvoltage tolerance on the input, which provides protection when
voltages of up to 7V are applied, regardless of the supply voltage. This
allows the MC74VHC1GT66 to be used to interface 5V circuits to 3V
circuits.
