MC74VHC1GT66,
NLVHC1GT66
SPST (NO) Normally Open
Analog Switch
The MC74VHC1GT66, NLVHC1GT66 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 V_CC to GND).
The MC74VHC1GT66, NLVHC1GT66 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 (R_ON) are much lower and more linear over input
voltage than R_ON of the metal−gate CMOS or High Speed CMOS
analog switches.
The newer NLVHC1GT66 offers the same functionality in a
1.2x1.0x0.55 mm UDFN6 package.
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, NLVHC1GT66 to be used to interface 5 V circuits
to 3 V circuits.
