74HC2G66; 74HCT2G66
Dual single-pole single-throw analog switch
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.
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
CMOS low power dissipation
High noise immunity
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
-
Complies with JEDEC standards:
JESD8C (2.7 V to 3.6 V)
