1. General description

The 74HC2G66; 74HCT2G66 is a dual single pole, single-throw analog switch. Each

switch has two input/output terminals (nY and nZ) and a digital enable input (nE). When

nE is LOW, the analog switch is turned off. Inputs include clamp diodes. This enables the

use of current limiting resistors to interface inputs to voltages in excess of V

2. Features and benefits

 Wide supply voltage range from 2.0 V to 10.0 V for 74HC2G66

 Very low ON resistance:

 41  (typ.) at V

=4.5V

 30  (typ.) at V

=6.0V

 21  (typ.) at V

=9.0V

 High noise immunity

 Low power dissipation

 25 mA continuous switch current

 Multiple package options

 ESD protection:

 HBM JESD22-A114F exceeds 2000 V

 MM JESD22-A115-A exceeds 200 V

 Specified from 40 Cto+85C and 40 Cto+125C
