General description
74AHC1G66 and 74AHCT1G66 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.

Features
■ Very low ON resistance:
   ◆ 26 Ω (typ.) at VCC = 3.0 V
   ◆ 16 Ω (typ.) at VCC = 4.5 V
   ◆ 14 Ω (typ.) at VCC = 5.5 V
■ High noise immunity
■ Low power dissipation
■ Balanced propagation delays
■ Multiple package options
■ ESD protection:
   ◆ HMB JESD22-A114E exceeds 2000 V
   ◆ MM JESD22-A115-A exceeds 200 V
   ◆ CDM JESD22-C101C exceeds 1000 V
■ Specified from −40 °C to +85 °C and −40 °C to +125 °C
