74HC2G66 74HCT2G66 Dual single-pole single-throw analog switch Rev. 10 3 October 2013 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 V . CC 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 =4.5 V CC 30 (typ.) at V =6.0 V CC 21 (typ.) at V =9.0 V CC 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 3.
