MC74VHC1GT66
SPST (NO) Normally Open
Analog Switch
The MC74VHC1GT66 is a Single Pole Single Throw (SPST)
analog switch. It achieves high speed propagation delays and low ON
resistances while maintaining 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 High Speed CMOS MC74VHCT4066 and the metal−gate CMOS
MC14066. 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 V CMOS logic to 5 V CMOS logic or from 1.8 V CMOS logic
to 3 V 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 7 V are applied, regardless of the supply voltage. This allows the
MC74VHC1GT66 to be used to interface 5 V circuits to 3 V circuits.
