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
