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 b ilateral 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 t w o ports)
when C is held low. It can be used in many
application as Battery P owered System, T est
Equipment. It’s available in the comm erc ial and
extended temperature range in SOT23-8L
package. All inputs and output are equipped with
protection circuits against static discharge, gi v ing
them ESD immunity and tra nsient excess voltage.

CAPACITIVE CHARACTERISTICS

1) CPDis defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. I
