Description
The 74V2T66 is an advanced high-speed CMOS
dual bilateral switch fabricated in silicon gate
C
2
MOS technology. It achieves high speed
propagation delay and very low on resistances
while maintaining true CMOS low power
consumption. This bilateral switch handles rail to
rail analog and digital signals that may vary
across the full power supply range (from GND to
V
CC
)

The C input is provided to control the switch and
it’s compatible with standard CMOS output; the
switch is ON (port I/O is connected to Port O/I)
when the C input is held high and OFF (high
impedance state exists between the two ports)
when C is held low. It can be used in many
application as Battery Powered System, Test
Equipment. It’s available in the commercial and
extended temperature range in SOT23-8L
package. All inputs and output are equipped with
protection circuits against static discharge, giving
them ESD immunity and transient excess voltage.

Maximum rating
stressing the device above the rating listed in the “absolute maximum ratings” table may
cause permanent damage to the device. these are stress ratings only and operation of the
device at these or any other conditions above those indicated in the operating sections of
this specification is not implied. exposure to absolute maximum rating conditions for
extended periods may affect device reliability. refer also to the STMicroelectronics sure
program and other relevant quality documents.
