MC74VHC1G66/D
MC74VHC1G66
SPST (NO) Normally Open
Analog Switch
The MC74VHC1G66 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 MC74VHC1G66 is compatible in function to a single gate of
the High Speed CMOS MC74VHC4066 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 ON/OFF control inputs are compatible with standard CMOS
outputs. The ON/OFF control input structure provides protection when
voltages between 0 V and 5.5 V are applied, regardless of the supply
voltage. This input structure helps prevent device destruction caused by
supply voltage − input/output voltage mismatch, battery backup,
hot insertion, etc.
