74HC1G66 74HCT1G66 Single-pole single-throw analog switch Rev. 04 19 December 2008 Product data sheet 1. General description 74HC1G66 and 74HCT1G66 are high-speed Si-gate CMOS devices. They are single-pole single-throw analog switches. The switch has two input/output pins (Y and Z) and an active HIGH enable input pin (E). When pin E is LOW, the analog switch is turned off. The non-standard output currents are equal to those of the 74HC4066 and 74HCT4066. 2. Features n Wide supply voltage range from 2.0 V to 10.0 V for the 74HC1G66 n Very low ON resistance: u 45 (typ.) at V = 4.5 V CC u 30 (typ.) at V = 6.0 V CC u 25 (typ.) at V = 9.0 V CC n High noise immunity n Low power dissipation n Multiple package options n ESD protection: u HBM JESD22-A114E exceeds 2000 V u MM JESD22-A115-A exceeds 200 V n Specied from -40 Cto+85 C and -40 C to +125 C 3.
