Product data sheet
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 VCC.
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 VCC = 4.5 V
30 (typ.) at VCC = 6.0 V
21 (typ.) at VCC = 9.0 V
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 C to +85 C and 40 C to +125 C
